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

1. Loading-status detection switch (S101 on the LOAB assy) are detected
by the microprocessor (IC601 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 IC101-pin 20 is +3V and IC601 (microprocessor) -
pin 83 is +3V, 650nm laser diode for DVD oscillates in the DVDM Assy.
When the voltage of IC101-pin 20 is +3V and IC601 (microprocessor) -
pin 83 is 0V (GND), 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 (KEYL assy), with the
above requirements satisfied. co
2. When the cover is open, close viewing through the objective lens with
.
the naked eye will cause exposure to the laser beam.
