SAFETY INFORMATION

LABEL CHECK

Name label

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

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

Additional Laser Caution

: See page 35.

· Laser diode is driving with Q1307 (650 nm LD) and Q1308

(780 nm LD) on the 4IN1 MOD ASSY.

Therefore, when short-circuit between the emitter and

collector of these transistors or the base voltage is supplied

for transistors turn on, the laser oscillates. (failure mode)

· In the test mode

, there is the mode that the laser oscillates

except for the disc judgment and playback. LD ON mode in

the test mode oscillates with the laser forcibly.

2. When the cover is open, close viewing through the objective

lens with the naked eye will cause exposure to the laser beam.
