SAFTY INFORMATION

A

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 trainedto 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 mayvoid the warranty. If you are not qualified to perform the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician.

B

C

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

LASER DIODE CHARACTERISTICS

FOR DVD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 650 nm

FOR CD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 780 nm

by the microprocessor (IC601 in the DVDM assy).

• To permit the laser diode to oscillate, it is required to set the loadingstatus detection switch for the clamp position (the center terminal of S101 is shorted to +3V). When the voltage of IC101-pin 20 is +3V, IC601 (microprocessor)

-pin 83 is +3V and IC601-pin 84 is +3V, 650nm laser diode for DVD oscillates in the DVDM Assy.

When the voltage of IC101-pin 20 is +3V, IC601 (microprocessor)

-pin 83 is 0V (GND) and IC601-pin 84 is +3V, 780nm laser diode for 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 (S104 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.

∗ : See page 61.
