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.
