SAFETY INFORMATION
LABEL CHECK
A

WARNING! Laser Pickup specifications and
The laser component is capable of emitting radiation exceeding Laser characteristics
the limit for CLASS 1. A specially instructed person should do
servicing operation of the apparatus. For CD
Wave length : 785nm
Operating output :
Read mode : 1.07mW (CW), Class1
Maximum output : Class1M

For DVD
Wave length : 660nm
Operating output :
B Read mode : 1.08mW, Class1
Write mode : 21.89mW (Pulse), Class1M
Maximum output : Class2M

Additional Laser Caution
1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detecting the loading state are detected
by the drive CPUs, and the design prevents laser diode
D oscillation when the CLAMP signal turns OFF.
In normal operation, if no disc is clamped, the laser diode
oscillation is disabled.
However, the interlock does not always operate in the test
mode.

2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 3A
laser beam.
