SAFETY INFORMATION
[I

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it-
yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained
to properly and safely repair complex products such as those covered by this manual.

Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.

WARNING! LASER DIODE CHARACTERISTICS 7
THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN FOR DVD 1 MAXIMUM OUTPUT POWER :5 mW
CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING WAVELENGTH 1650 in
THE LIMIT FOR CLASS 1. FOR CD: MAXIMUM OUTPUT POWER :5 mW
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE WAVELENGTH I 730 1
APPARATUS.
LABEL CHECK - Additional Laser Caution

. Loadingrstatus detection switch (S101 on the LOAB assy) are detected
by the microprocessor (lC601 in the DVDM assy).
- To permit the laser diode to oscillate, it is required to set the loading,
status detection switch for the clamp position (the center terminal of
S101 is shorted to +3V).
When the voltage of lC101rpin 21 is +3V, l0601 (microprocessor)
pin 83 is +3V and l0601rpin 84 is +3V, 650nm laser diode for DVD
oscillates in the DVDM Assy.
When the voltage of lC101rpin 21 is +3V, l0601 (microprocessor)
pin 83 is 0V (GND) and I0601rpin 84 is +3V, 780nm laser diode lor
CD oscillates in the DVDM Assy.
In the test mode ' , the laser diode oscillates when microprocessor
detects a PLAY signal, or when the PLAY key is pressed (8104 ON in
the FLKY assy), with the above requirements satisfied.

2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.
