Beforesing this unit please read these operating instructionscarefully. Take special care to follow the warnings indicated onthe unit itself as well as the safety suggestions listed below.Afterwards keep them handy for future reference.

Power Source -- The unit should be connected to power sup-ply only of the type described inthe operating instructions oras marked on the unit.

2. Polarization -- If the unit is equipped with a polarized ACpower plug (a plug having one blade wider than the other),that plug will fit into the AC outlet only one way. This is a safe-ty feature. If you are unable to insert the plug fully into theoutlet, try reversing the plug. If the plug should stil l fail to fit,contact your electrician to replace your obsolete outlet. Donot defeat the safety purpose of the polarized plug.

3. Power Cord Protection -- AC power supply cords should berouted so that they are not likely to be walked on or pinchedby items placed upon or against them. Never take hold of theplug or cord if your hand is wet, and always grasp the plugbody when connecting or disconnecting it.

4. Nonuse Periods -- When the unit is not used, turn the poweroff. When left unused for a long period oftime, the unit shouldbe unplugged from the household AC outlet.

InstallationEnvironment1. Outdoor Antenna Grounding -- If an outside antenna iscon-

nected to the receiver, be sure the antenna system is ground-ed so as to provide some protection against voltage surgesand built-up static charges. Section 810 of the National Elec-trical Code, ANSIINFPA No. 70-1990, provides informationwith respect to proper grounding of the mast and supportingstructure, grounding of the lead-in wire to an antennadischarge unit, size of grounding conductors, location ofantenna-discharge unit, connection to grounding electrodes,and requirements for the grounding electrode. See figurebelow.

3. Heat -- The unit should be situated away from heat sourcessuch as radiators and the like.It also should not be placed in temperatures less than 5C(41F) or greater than 35C (95F).

Placement1. Venti lation -- The unit should be situated so that its location

or position does not interfere with its proper ventilation. Allow10 crn (4") clearance from the rear of the unit.2. Foreign Material -- Care should be taken so that objects donot fall intoand _iquids are not spil led into the unit. Do not sub-ject this unit to excessive smoke, dust, mechanical vibration,or shock.

3. Magnetism -- The unit should be situated away from equip-ment or devices that generate strong magnetism.

4. Stacking -- Do not place heavy objects, other than systemcomponents, on top of the unit.

PleaseheckandidentifyhesuppliedaccessoriesListening caution@Selecting fine audio equipment such as the unit you've just pur-chased isonly the start of your musical enjoyment. Now it's timeto consider how you can maximize the fun and excitement yourequipment offers. This manufacturer and the Electronic In-dustries Association's Consumer Electronics Group want you toget the most out of your equipment by playing it at a safe level.One that lets the sound come through loud and clear without an-noying blaring or distortion- and, most importantly, without affec-ting your sensitive hearing.Sound can be deceiving. Over t ime your hearing "comfort level"adapts to higher volumes of sound. So what sounds "normal"can actually be loud and harmful to your hearing.Guard against this by setting your equipment at a safe levelBEFORE your hearing adapts.To establish a safe level: Start your volume control at a low setting. Slowly increase the sound until you can hear itcomfortably andclearly, and without distortion.Once you have established a comfortable sound level: Set the dial and leave it there.Taking a minute to do this now will help to prevent hearingdamage or loss inthe future. After all, we want you listening for alifetime.We Want You Listening For A LifetimeUseclwisely, your new sound equipment will provide a lifetime offun and enjoyment. Since hearing damage from loud noise isoften undetectable until it is too late, this manufacturer and theElectronic Industries Association's Consumer Electronics Grouprecommend you avoid prolonged exposure to excessive noise.This list of sound levels* is included for your protection.*The level used here is different from that displayed on thesystem's display.DecibelLevel

(Refer to page 20 for tuning.)-Before presettingHow many broadcast stations can be preset?A total of 30 FM and AM stations can be preset.How Is presetting done?The two following methods are available. Automatic memory presetting

Automatic memory preset ting allows this unit to automatical-ly search for broadcast stations and then preset them intomemory.With this function, searching proceeds from the frequencycurrently being displayed and continues through higher fre-quencies, (up to 107.9 MHz for FM, up to 1710 kHz for AM)and broadcast stations are preset in the order in which theyare located.With this method, the channel ranges that can be preset intothe memory for different bands (FM or AM) are set asfollows.
