1. Function

1.1 Design philosophy

CYPRES, an acronym for "CYbernetic ParachuteRElease System", is an automatic activation devicewhich meets all needs, requirements, and desiresof today's parachutists. Once it is installed, youcan't hear it, you can't feel it and you can't see it.The operation is quite simple: Just switch it onprior to the first jump of the day, then forget aboutit. It is not necessary to switch it off, becauseCYPRES will do this itself.When not operated in Military mode, the weatheris constantly checked by CYPRES over the day bymeasuring the air pressure twice a minute. Thismeans that the unit is always calibrated to theprecise ground level.The Unit is designed in a way that it won't restrictthe parachutist in any way. CYPRES will even copewith extreme maneuvers during exit and in freefall.Whatever you can think of under canopy like stalls,spiral turns, down planes, as well as any CRW,CYPRES will analyze these movements without

problems. It won't interfere with any normalactivities while skydiving.Only freefall at a very low altitude will causeCYPRES to take action. In this situation CYPRESis designed to activate the reserve approx. 4.5seconds prior to impact.The CYPRES family of AAD‘s work with aremarkable reliability. To date, as production ofCYPRES 1 comes to an end during spring 2003,CYPRES units have saved the lives of more than1000 parachutists, without a single unit everrefusing to activate when the conditions were met.CYPRES 2 is the next generation of the mostreliable piece of parachute equipment everproduced.


As the next generation of CYPRES, CYPRES 2combines tried and true quality and reliability withnew achievements, technology and discoveriesmade during the past 12 years of continued researchand development. CYPRES 2 offers numerous ad-ditional features and attributes including:

• unit is water resistant for 15 minutes at a depthof 15 feet (5 meters) in fresh and saltwater.

• power supply of CYPRES 2 is maintenance-free for the user. There is no need to observea replacement date, record the number ofjumps made, monitor the voltage during self-test, watch for a `low bat' sign, purchase abattery, or have a rigger open or repack thereserve for this reason.

• unit serial number accessible from the display.

• maintenance due date accessible from thedisplay.

• reminds you of the maintenance when closeto the due date.

• smaller and lighter.

• robust, rigger friendly case, with roundedcorners and edges.

• extended maintenance window: +/- 6 monthsfrom month of manufacture, no down-timeduring the busy part of the year regardless ofmonth of manufacture.

• self test is completed in 10 seconds.

The handling of the CYPRES 2 is simple:After you have purchased it, the rigger slides itinto the factory integrated CYPRES set up(pouches and cable chanels in the harness/container) and you forget about it for 4 years*Then you have the maintenance done and forgetabout it for another 4 years.*Then you have another maintenance done andforget about it for another 4 years. *

* Except for switching it on at the beginning ofthe day, and changing the filter if you have landedin water.


1.2 Components

CYPRES consists of a control unit, a processingunit and one release unit (cutter) for 1-pin reservecontainer or two release units (cutters) for 2-pinreserve container.

The CYPRES 2 Military Unit is designed

- ENTER the training mode by switching on theCYPRES 2: click, click, click, click. That's it. Thereis nothing more to do. -

This features the normal CYPRES 2 Expertproperties with all its incredible convenience andreliability.

Ideal whenever you are doing typical trainingjumps.That means when you go to an airfield or a DZ,enter your airplane or helicopter, do a descent,repack there, do another jump and maybe more.No matter how many jumps you do and what kindof parachuting activity you carry out, the onlyattention that your CYPRES 2 Military Unitrequires is your click, click, click, click switchingon procedure before your first jump of the day.

The CYPRES 2 Military Unit in the training modetakes care of all meteorologic influences duringthe day (even a bad weather front with it’s extremepressure changes).

As this is probably the main application, theCYPRES 2 Military Unit is particularily welladapted and requires no attention after switch on.

- ENTER the operation mode by keeping thepush button pressed after the last switch-on clickand chosse the intended landing elevation -

This feature of the CYPRES 2 Military unit allowsto protect the parachutist during every militaryoperation that you can think of.

The unit can be set to every DZ on this globe,whether it is the Dead Sea in Syria or on theHimalaya in Asia or even a higher virtual DZ on aHaHo jump.

It is possible to do the programming prior the take-off to another DZ elevation, while still beeing onthe ground.

Or you can choose your DZ while you are alreadyin flight and then programm it at altitude.

Or you can choose your DZ while you are alreadyin flight in an active pressurizee cabin andprogramm it there.

The way to get that done is as simple as you canthink of.You just enter the airpressure value of your targetDZ into your CYPRES 2 Military Unit.The setting is intuitive, faulty-tolerant and takesless than 45 seconds.

A number of tools (circular calculator, PDA) areavailable to help you in finding the right settingfor any place in the world. The use of these toolsis easy and can be learned in a few minutes.

1.5 Operational safety

There are two important points to rememberregarding the operational safety of CYPRES:

1. CYPRES self-tests automatically every time itis switched on. After every switch-onprocedure, CYPRES executes a self-test routineduring which all important internal functionsare checked. A positive outcome to this self-test gives you the best possible assurance for atrouble-free operation for up to 14 hours.When the display unit shows 0–, the self-testhas been completed successfully. If the self-test has detected an error or discrepancy,CYPRES will not assume operating mode butwill switch itself off after displaying an errorcode. This error code indicates why the self-test process was aborted (see chapter 5).

1.4 Power supply

No attention is needed to the power supply ofCYPRES 2.The unit is designed to function from the date ofmanufacture until the first maintenance, from thefirst maintenance to the second maintenance andfrom the second maintenance until the end of lifewithout limitations as long as the unit is used forparachuting. Should CYPRES 2 cease to workdue to a faulty power supply prior to themaintenance due date, Airtec will take care of thiswith the highest priority.


2. CYPRES has fail-safe error detection. Twoprocesses are activated in CYPRES once theunit has been switched on: a primary workingprocess and an independently operatingcontrolling process that monitors the workingprocess continuously. In case of errors whilethe working process is active, the backupcontrolling process will switch the unit off.Depending on the type and potential impact ofthe error, CYPRES can either be switched onagain or it will stay in shut-down mode per-manently. With certain error codes (see Chapter5), it is not possible for the user to reactivatethe unit. In these cases, CYPRES must be sentto the manufacturer or service center forinspection and adjustment.

2. Product overview

CYPRES 2 Military is available in the followingstandard models:

1000/35 A

1500/35 A

4. How to operate CYPRES 2

4.1 Handling the control unit

The push button on the control unit should bepressed with the fingertip; please do not use afingernail or any other object. Use a short clickaction in the middle of the button.

Please familiarize yourself with switchingCYPRES 2 on and off (see chapter 4.2) andchanging altitude reference (see chapter 4.4) priorto use.The push button is the only means the user has tocontrol CYPRES 2 functions. For a parachutistnecessary handling is reduced to the followingsixactions:

• switch on

• switch off

• increase altitude reference

• decrease altitude reference

• display the serial number

• display the next maintenance date

The following sections provide thoroughdescriptions of these six actions.


4.2 Switching CYPRES on

CYPRES is switched on by clicking the pushbutton four times with very short clicks. Start theswitch-on cycle by clicking the button once. Afterapprox. one second, the red LED-light will glow.You must acknowledge the red light immediatelyby clicking the button again. This sequence - a clickfollowing appearance of the red light - will berepeated two more times. After a total of fourclicks, CYPRES goes into self-test mode.If you do not act promptly after seeing the LED-light, or if you push the button to soon, CYPRESwill ignore the switch-on attempt.This four-click initiation cycle has been designedto avoid accidental switch-on.

wait!click wait! wait!click click

Once the switch-on procedure is finished, the unitwill run through its self-test. Initially, the displaywill show the number “10“, and then a countdownending with “0“. Between displaying “1“ anddisplaying “0“ CYPRES shows the actual ambientairpressure. When the “0“ with the arrow downis shown, the unit is functional for the next 14hours. After 14 hours have passed, the unit willswitch itself off automatically. A manual switch-off is always possible using the push button. Ifthe self-test is not successful, an error code isshown on the display for approximately 2 seconds.The meaning of this error code can be read inchapter 5.The manual switch-off sequence is identical tothe switch-on procedure (click, light, click, light,

click, light, click). This routineis designed to avoid accidentalswitch-off.

self-test andcalibration


In the training mode, CYPRES must be switchedon at the takeoff site on the ground. It must neverbe switched on inside an flying aircraft, helicopter,balloon, etc.To reset CYPRES, switch off and then on again.The unit will then re-calibrate and “zero“ itself tothis elevation.

When the takeoff airfield and intended dropzoneare on the same location and all jumping activityis restricted to that place, an initial switch-on atthe dropzone will suffice for any number of jumps,provided they all take place within 14 hours.Should any of the following situations occur,CYPRES must be reset before the next jump:

• The dropzone is missed and the landing takesplace in an area with an elevation greater than30 feet (10 m) above or below the dropzonelevel. Or, on the return journey to the dropzonethe ground elevation changes similarly.

• The unit is taken away from the airf ield/dropzone by vehicle or carried by hand andlater brought back again.

• If the total time for a single jump (takeoff tolanding) exceeds one and a half hours,CYPRES will function normally, but must bereset after landing.

General recommendation: If you have a doubt,reset CYPRES.

4.3 Using CYPRES in the Training mode


Whenever you want to land at a DZ elevation thatis different from your takeoff elevation, you mustuse the operation mode of your CYPRES 2 Mili-tary Unit. The only information that your CYPRES2 Military Unit needs is the air pressure of yourtarget DZ.Get the information from your pilot, meteorologistor your officer in charge.This value has to be programmed in.

How can you enter this value in the CYPRES 2?

So: Switch on the unit and hold the push buttonpressed until immediately after the selftest thenumber "1000" appears.The "1" alternates with "0". Let the button goto choose "0" or "1".The choosen figure remains visible on thedisplay.

Press the button again - The second digitcounts from "0" through "9".Let the button go at the choosen figure. Thisfigure remains visible on the display.

Press the button again - The third digit countsfrom "0" through "9".Let the button go at the choosen figure. Thisfigure remains on the display.

Press the button again - The fourth digit countsfrom "0" through "9".Let the button go at the choosen figure. Thisfigure remains on the display.

If you missed a figure, just keep the finger onthe button until the figure shows up again.(After "9" the display restarts automaticallywith "0".)

DZ at 910 hPA

4.4 Using CYPRES in the Operation mode


The pressure adjustment and the display indicationremains until the unit is switched off . If you haveto change your setting, you must switch theCYPRES off and on again.

If you try to enter a pressure of less than 200 hPa(approx. 39.000 feet above sea level) or more than1.075 hPa (approx. -1.600 feet below sea level),the CYPRES switches itself off. The blank displayindicates that the desired adjustment is outside thespecified parameters.


If the atmospheric (absolute) air pressure valuesto perform the altitude adjustment are notknown, it is possible to do the altitudeadjustment using the ft/hPa-(or m/hPa-)calculator. This calculator can be orderedseparately and is available in differentlanguages.When using the calculator, the following vitalpoints are to be considered:

• Use this calculator for 'AbsoluteAdjustment' Military CYPRES Units only('Abs. Adj.' or ‘A’ nomenclature on ControlUnit)

• Small inaccuracies can occur with the useof this calculator because of its' physicalproperties.

• Greater accuracy can be achieved with theuse of the PC Based ‘Excel' spreadsheetcalculator or by utilizing the on-linecalculator that can be found atwww.militarycypres.cc

4.4.1 Using the circular calculator

circularcalculatorinches Hgscale

circularcalculatormbarscale


The altitude adjustment using the calculator is doneas follows:

1.) Rotate discs so the Arrow points to the currentaltimeter setting at the target (virtual) DZ.

e.G. DZ altimeter setting = 30.15 inches HG

2.) Keeping the discs carefully aligned, find the(virtual) DZ field elevation above sea level (feetMSL) on the inner disc.

e.G. DZ elevation = 7000 feet MSL

The number aligned with this elevation on theouter disc is the setting in mbar for the Absolu-te Adjustment Military CYPRES


4.4.2 Using the PDA computer

If the atmospheric (absolute) air pressure values toperform the altitude adjustment are not known, itis possible to do the altitude adjustment using theiPAQ CYPRES Military Absolute Calculator. Thiscalculator can be ordered separately.

Using:

• Enter the altimeter setting of where you are(in either hg or mbar)

• Enter the elevation at the Virtual Dop Zone(in either feet or meter)

• Select from the drop down box the elevationscale (either feet or meters)

• Click the ‘Calculate!’ button

• The value for the CYPRES setting is displayedin the box


4.5 Access to unit information

CYPRES 2 provides an easy way to view the serialnumber and next maintenance due date.Simply perform an unvalid altitude reference (lessthan 200 hPa or more than 1075 hPa).

After that your CYPRES 2 Military Unit will showyou its serial number for 5 sec.Than the display will go blank and after that themonth and year of the next maintenance due datewill be shown for 5 sec.

next maintenance due in 05 / 2007

4.6 CYPRES 2 and Water jumps

The design of the CYPRES 2 allows water jumpswithout removal of the unit. CYPRES 2 is waterresistant up to a water depth of 15 feet (5 meters) fora duration up to 15 minutes. This is achieved througha water resistant casing, sealed plug connections, asealed cutter, a sealed control unit, and a special filter.The filter allows precise measurement of the airpressure and at the same time keeps water away fromthe inside of the unit. As long as there is no contactwith water, the filter never needs to be replaced bythe user.If water did enter into the filter, the filter must beremoved and a new filter installed.CYPRES 2 comes with one spare filter and a filterchanging tool. The CYPRES 2 filter changer tool ismade from stainless steel, specifically for thepurpose of filter removal and replacement. Filterreplacement (see chapter 4.7) can be done by yourrigger (packer). After water contact, the rig and thereserve must be dried according to the manufacturersinstructions. After that the rig and CYPRES 2 withthe new filter can be used again.


4.7 Changing the filter

Filter Removal: Hold the CYPRES filter changerat the non-slotted end and push it straight (withouttilting) onto the filter up to the stop position.

Tightly grip the filterchanger, twist off byturning in a counter-clockwise direction andremove the f ilter. Ifthere is water in thecasing groove (behindthe filter), dry it with a

cloth. Remove the old filter from the filter changerby pushing with your finger or with the eraser endof a pencil. Discard it.

Filter Installation: Place the new filter with thelabeled side toward and into the slotted end of thefilter changer up to the stop (flush) position. Donot angle.

Hold the filter changer by the non-slotted end,gently slide the filter fitting into the unit holdingit straight without tilting. Turn the filter changerclockwise, initially there will be little resistance.Continue turning the filter changer until it slipson the filter. (The filter stops turning but thechanger continues to turn.) Remove the filterchanger from the filter by pulling straight back.

Do not use other tools !


The switch-on procedure can be performed severaltimes after a “3333“ error was displayed. If the 0– isdisplayed, the unit is fully functional and can be usedfor skydiving.

If other than these three described numbers appearin the display, or if the unit switches itself off andcan not be switched on again, please contact Airtecor SSK.Please record the error code number!

5. Error Display

If an error condition is detected during the self-testcountdown, CYPRES 2 displays a code number onthe display for approx. 2 seconds, then it switchesitself off. (Display goes blank).

Error code number / error code description:

One or both of the attached release units arenot correctly electrically connected to theunit. The reason may be a cable break, thecutter plug could be disconnected, or therelease unit(s) may have activated.

Excessive variations in ambient air pressurehave been measured during the self-testperiod. The unit is unable to obtain consis-tent values for the ambient air pressure atground level. Possible reasons could be anattempt to switch on CYPRES in the trainingmode in a car, driving uphill or downhill,in an elevator or in an airborne aircraft.

6. Changing the release unit(s)

After an activation the release unit can be changedby any rigger (packer) via the plug-and-socketconnection.

Disconnecting the release unit:Hold plug and socket by their aluminium grips andpull them apart using a smooth straight motion.Do not twist!

Connecting the release unit(s):Hold plug and socket by their aluminium grips.Place the plug directly in front of the socket andconnect them by pushing together with a smoothstraight motion until it is completely seated. Donot twist!

It is easy to change a 1-pin CYPRES to a 2-pinCYPRES or vice-versa, by swapping cutter types.

1-pin Cutter 2-pin Cutter


Notes:

1. CYPRES 1 field replaceable cutters (no alu-minum grip) can be used with CYPRES 2.They will function properly, however this combi-nation is not water-resistant.CYPRES 2 cutters (identified by aluminumgrip) can be used with any CYPRES 1 with thefield replaceable cutter connector. They functionproperly - but this combination is not water-resistant.

2. Release units (cutters) have a serial number on aheat shrink tubing placed on the cable. Thisnumber identifies the cutter. A table of cutternumbers with their corresponding dates ofmanufacture will be available at www.cypres.cc

3. It is possible that the cutter plug separates fromthe socket after a CYPRES activation. In therare combination of this event and a waterlanding, the socket must be dried out before furt-her use. Do that by tapping the open end of thesocket onto a flat surface such as a table top.Once no additional water comes out while

WARNING! Do not use release units(cutters), with an expired lifetime!(Older than 12 years and 6 months)

Release units (cutters) also requiretechnical service (maintenance) everyfour years.Please send cutters more than fouryears old, that have not been attachedto a CYPRES during maintenance toAirtec or SSK for a free no-chargeinspection prior to use.

tapping on the table top, store the CYPRES withthe open end of the socket hanging downwardfor another 24 hours in a dry area, to allow thesocket to dry out completely. When completelydry, insert the plug of the new cutter. Never insertan object (i.e. Q-tip) to dry out the plug.

4. Use a one-pin cutter in a one-pin container anda two-pin cutter in a two-pin container.


7. Technical service

The extremely reliable function of CYPRES isbased on 4 facts: exclusive use of carefullypretreated and approved parts, strict and detailedmanufacturing procedures, continuous qualitycontrol and monitoring through the manufacturingprocess, and regular periodic technical service(maintenance). 4 and 8 years after the original dateof manufacture, maintenance proceduresaccording to the manufacturers guidelines arenecessary. There are 4 primary reasons for themaintenance:

1. Deviations between nominal and actual valuesare corrected to ideal values. Every detail isobserved. It is common that signs of wear andtear are corrected and sometimes even‘cosmetic’ treatment is done.

2. The technical condition of each unit is analyzed.The fact that a very high percentage of unitsare returned for the periodic maintenance givesthe ability to see statistical trends and to predictpotential problems at a very early stage. The

advantage: it is often possible to preventsituations by modif ications during themaintenance procedures, rather than having tofix problems with downtime later.

3. Experience shows that during a period of 4years, changes and improvements do happen.Applicable updates are performed duringmaintenance. Such updates may have thebackground of technical improvements, orenhancement of knowledge, or may result fromenvironmental changes, which Airtec is alwaysresearching and taking into consideration.

4. The most important part of the maintenance isthe individual pre-adjustment of each unit forthe next 4 years. A unit will not be returnedbefore a high confidence level is reachedregarding the prediction of the unit’s properfunction for the next 4 years.


At any time it’s possible to check the date of the nextmaintenance by holding the button down at the lastclick during the switch on procedure until you see‘next maint. inmonth / year’. (See chapter 4.5)

If the unit enters the 6 month period before amaintenance due date, themaintenance date (nextmaint. in month / year) willautomatically be shown ateach selftest. 6 months afterthe due date the display willchange to: ‘next maint.now’.

All displayed dates are only a reminder.Please choose a suitable date during the 13 monthtime frame for a convenient performance of themaintenance. According to our experience, thenumber of maintenances and the necessary timeto do them increases between February and May.For quicker service, a date between June andJanuary is a better choice.

The maintenance has to be performed 4 and 8 yearsafter the original date of manufacture. The earliestpossible date for the CYPRES 2 maintenance is 6months early, the latest 6 months after the monthof manufacture.

A delayed maintenance has no advantage. It doesnot save any cost, nor will the total lifetime of theunit be extended. It’s smart to choose a suitabletime during the 13 month window for sending theunit in for maintenance, rather than waiting untilthe last possible moment, or until the beginning ofthe next season.Because of the 50,000+ maintenance proceduresperformed to date on CYPRES, and changesincorporated into the design of CYPRES 2, Airtechas determined that it is possible to extend themaintenance window to 13 months on CYPRES 2.This maintenance window gives you more freedom,and avoids maintenance down-time at the wrongtime of the year - please use this new feature wisely!


After the 8-year maintenance, CYPRES 2 shouldbe airworthy until the end of life. The expectedlifetime of CYPRES 2 is 12 years from date ofmanufacture.

CYPRES 2 maintenance cost is a flat-rate (alwaysthe same), even when a unit requires extensiverepairs. During the lifetime of a CYPRES 2 unit,the parachutist should not have any operation costsother than the 2 maintenance fees (except for anyrequired replacement cutters or water resistantfilters).

Please contact your local CYPRES dealerconcerning the maintenance. Please contact Airtecwhen you don’t know who your local dealre is.

8. Important Notes

8.1 Important notes for jump pilots

The following 3 points have only than to be takeninto account if the CYPRES 2 Military Unit is usedwithout altitude adjustment (in Training mode).

• Every CYPRES 2 Military Unit has to exceedan altitude of more than 1500 feet above itsfiring altitude to become fully armed.

• Never descend to an altitude below the airfieldtakeoff elevation.

• If the aircraft can be pressurized, make surethat the cabin remains open when the turbinesare started up. Leave a window, a door, or theramp open slightly until after lift-off. Makesure that the cabin pressure cannot build upabove the air pressure on the ground. (Hint:the parachutist’s altimeters should never gobelow "0".)

Always:Stay below the vertical activation speed in theactivation window (6900 feet/min or 5700 feet/min for 2500/29/A CYPRES) if you are on descentin an aircraft.


The sketch below shows what must not be done / should be done when the unit is used withoutaltitude adjustment (in Training mode)

min.1500 ftNO !

If the CYPRES 2 Military Unit is used with an altitude adjustment (in Operation mode), theabove mentioned limitations do not apply.

- Never fly below the airfield takeoff elevation.- Always go at least 1500 feet above the activation altitude.

8.2 Important notes for users

• CYPRES must not be used for parascendingor paragliding/sailing.

• CYPRES cannot be used for base jumps (jumpsfrom fixed objects), and must be switched offprior to making a base jump.

• To make sure that a CYPRES 2 Military deviceis armed when it is used in the training mode,you must fly at least 1500ft above the presetf iring altitude (thumb of rule. Exactspecifications available from Airtec / SSK). TheCYPRES 2 Military device is always armedwhen in the operation mode.

• CYPRES is shielded against radio transmittersignals. Extreme concerted efforts have beentaken to protect CYPRES 2 from “radiopollution“. Although the extraordinary shiel-ding system of CYPRES 2 has been inves-tigated thoroughly, it is impossible to have100% protection. It is still recommended toavoid strong radio transmitters. Please contactAirtec if you have questions.

• A release unit that has activated builds up ahigh internal pressure and will remain press-urized. Never attempt to open it by force. Itcan, however, be stored safely for an indefiniteperiod of time, provided it has not beendamaged.

• A good reserve pilot chute is an importantsafety factor. On systems with an internally-mounted pilot chute, we recommend thatowners equip their rigs with one that has beenAirtec tested and subsequently qualified byAirtec and the rig manufacturer. Typically therig manufacturer delivers these pilot chuteswith the rig. If there is any doubt, please contactAirtec.


9. Repacking of reserves

The following tips are only brief suggestions.Detailed instructions for riggers (packers) canbe found in our special publications. (“Rigger’sGuide for Installation“ and “CYPRES Packer’sChecklist“)

General:Please closely check the grommets at each repack.Grommets with rough edges will ultimately destroyany loop. Replace damaged grommetsimmediately. Only use original CYPRES loops /loop material, pull ups, and discs when a CYPRESis installed in the container. Even if you do nothave a CYPRES in your container, a CYPRES loopwill markedly improve your safety. Non adjustableloops which are attached to a CYPRES disc andare mounted in containers with internal pilot chuteshould be replaced at each repack. Repack cyclesare getting longer, so this increases your safetyinexpensively. After attachment to the disc,CYPRES loops should be treated with CYPRESloop silicone on the upper 4 centimeter. The loops

provided by Airtec are already impregnated on thefirst 4 centimeters.

1-Pin Pop Top:Please check the loop carefully and replace ifnecessary. On all adjustable loops, silicone shouldnot be used. The adjustment will not remain fixed.

2-Pin Pop Top:Since 1991 Airtec endorses the ‘Running Loop’for 2-Pin Pop Top rigs, an Airtec development. The‘Running Loop’ has the characteristic that evenwhen you pull one of the two pins, the pilot chutewill launch. Please ensure that a ‘Running Loop’is installed. The ‘Running Loop’ must be siliconed.A ‘Running Loop’ channel is available from Airtecat no cost.

Additional notes on the Racer from Jump Shack:On Racer systems in countries where US TSOstandards apply, you must use the quick loopsystem in accordance with the rig manufacturer'sinstructions. Do not use silicone on quick loops.


For all CYPRES loops including running loopsand quick loops, you must use genuine CYPRESloop material.

Tips for Riggers (packers):The ‘Packer’s Kit’ is available from CYPRESdealers. It contains a lot of things that make lifeeasier, including:50 meter spool of loop material, finger trappingneedles, discs, temporary pins, silicone, a User’sGuide and the ‘Packer’s Checklist’ with detailedinstallation instructions for nearly all sportcontainers, tips for packing of CYPRES equippedrigs etc.Further information on CYPRES installations andfor packing CYPRES equipped rigs can be foundat www.cypres.cc

10. Switching Rigs

Switching your CYPRES to another CYPRESready rig will require only a few moments of workfor your rigger.If the container swap requires a change in thenumber of release elements (cutters), this can bedone quickly on-site by unplugging the old cutterand swapping with the required type cutter (1-pinor 2-pin). It is not necessary to send the CYPRESto the manufacturer. The necessary cutter can bepurchased from any CYPRES dealer.

11. Regarding Air Travel

A CYPRES equipped rig may be transported infreight and passenger airplanes withoutrestrictions. All its components (e.g. measuringtechnique, electronics, power supply, loop cutter,control unit, plugs, cables, casing) as well as thecomplete system, contain parts and materials thatare approved by U.S. DOT and other competentagencies world-wide, and are not subject to anytransport regu-lations.Because of the size of a rig we recommend to checkit in as normal luggage and to not take it on boardas hand luggage. In case of questions or objectionsfrom the security personnel, please use the cardshown on the right which you’ll find in the backcover of this book. The card shows an X-ray of acomplete rig with CYPRES 2. Depending on typeand design of the rig the X-ray on the security’sscreen may vary.Presently, the Parachute Industry Association andthe USPA are working with the TransportationSecurity Agency concerning traveling withparachutes.

If you’ve lost the card, you can get a newone from Airtec or SSK.

14. Disclaimer

In designing and manufacturing CYPRES, the aimof Airtec GmbH is that the device should nevercause an accidental canopy opening, but shouldalways open a reserve container at an appropriatealtitude when the activation criteria are met.All investigations and experiments performedduring the product's development, and alllaboratory and field tests accompanying trial andproduction phases have shown to date thatCYPRES meets both requirements.However, the occurrence of a malfunction cannotbe excluded. We accept no responsibility fordamages and consequences resulting from anymalfunction.Airtec GmbH also accepts no responsibility fordamages or problems which are caused by the useof non original Airtec parts and supplies.

The use of CYPRES does not automaticallyprevent from injury or death. Risk can be reducedby assuring that each component has been installedin strict compliance with the manufacturer‘s

instructions, by obtaining proper instruction in theuse of this system, and by operating eachcomponent of the system in strict compliance withthis User‘s Guide.

Automatic activation devices (AADs) sometimesfail to operate properly, and sometimes activatewhen they should not, even when properly installedand operated. Therefore the user risks seriousinjury or even death to themselves and othersduring each use.By using or allowing others to use CYPRES, youacknowledge that you accept responsibility for theproper use of the device, as well as accepting theconsequences of any and all use of this device.Airtec GmbH, their Dealers, Service Centers, andAgents total and complete responsibility is limitedto the repair or replacement of any defective device.

CYPRES is strictly a backup device, and is notintended to replace proper training or timelyexecution of appropriate emergency procedures.
