CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous ra-diation exposure.

Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing• Keep the temperature of the soldering iron around 270 ˚C dur-

ing repairing.• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering

or unsoldering.

UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARKUnleaded solder has the following characteristics.• Unleaded solder melts at a temperature about 40 ˚C higher than

ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 ˚C .Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!• Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occursuch as on IC pins, etc.

• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

SELF-DIAGNOSIS RESULT DISPLAY MODEThis set uses the self-diagnostic function system in which if anerror occurred during the recording or playing, the mechanismcontrol block and the power supply control block in themicrocomputer detect it and record its cause as history in thenonvolatile memory.By checking this history in the test mode, you can analyze a faultand determine its location.Total recording time is recorded as a guideline of how long theoptical pickup has been used, and by comparing it with the totalrecording time at the time when an error occurred in the self-diagnosis result display mode, you can determine when the erroroccurred.Clear both self-diagnosis history data and total recording time, ifthe optical pickup was replaced.

• Self-Diagnosis Result Display Mode Setting Method

1. Set the test mode (see page 13).2. In the display check mode, press the [MENU] key activates the

self-diagnosis result display mode where the LCD display asshown below.

3. Then, each time the > key is pressed, LCD display descendsby one as shown below. Also, the LCD display ascends by onewhen the . key is pressed.

REWRITING THE PATCH DATA AT REPLACEMENT OF MAIN BOARD OR NONVOLATILE MEMORY(IC804)

This set requires the patch data in the nonvolatile memory (IC804) to be rewritten using the application, when the MAIN board ornonvolatile memory (IC804) was replaced.

Caution: The application that meets the microcomputer version in this set must be used when rewriting the patch data. Rewriting thepatch data using the application not suitable for the microcomputer version could cause the set to malfunction.For a checking method of the microcomputer version, see “SECTION 4 TEST MODE” (page 13).

• Preparation1. USB cable (attached to the set)2. Personal computer in which the Net MD Driver has been installed. (For further information, see “System requirements” (page 4) in

“SECTION 1 SERVICING NOTES”)3. Application “PatchWriter” for patch data rewriting

• How to Get the Application “PatchWriter” for Patch Data RewritingContact our service technical support division to get the application.

• Pre-check1. Check the microcomputer version in this set. (For a checking method of the microcomputer version, see “SECTION 4 TEST MODE”

(page 13).)2. Check that the Net MD Driver has been installed in the personal computer.3. Make sure that the set is in the Normal mode.

Note: Do not rewrite the patch data in the Test mode.

• Rewriting the Patch Data1. Connect the set to the personal computer with the USB cable.2. Start the application “PatchWriter”.3. Make sure that the following window opens.4. Click the [Usb Connect] button.
