1. SAFETY INFORMATION
WARNING
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
CLASS1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.
LASER DIODE CHARACTERISTICS
FOR DVD : MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 655 nm
FOR CD :
MAXIMUM OUTPUT POWER : 5mW
WAVELENGTH : 785 nm
Additional Laser Caution
1. Inside detection switch (S201 on the SMEB assy) and clamp-
status detection switch (S11 on the TRSB assy) are detected by
the microprocessor (IC11 in the DVDM assy).
• To permit the laser diode to oscillate, it is required to set the
inside detection switch for the inside position (S201 : ON) and to
set the loading-status detection switch for the clamp position (the
center terminal of S11 is shorted to +5V). The 655 nm laser diode
for DVD oscillation will continue if pin 19 of IC1 is shorted to +5V
(fault condition) in the DVDM assy.
The 785 nm laser diode for CD oscillates if pin 20 of IC1 is shorted
to +5V in the DVDM assy.
In the test mode
∗
, the laser diode oscillates when microproces-
sor detects a PLAY signal, or when the PLAY key is pressed
(S5817 ON in the KEYB assy), with the above requirements sat-
isfied.
2. When the cover is open, close viewing through the objective lens
with the naked eye will cause exposure to the laser beam.
