SAFETY INFORMATION
CAUTION
WARNING
Where in a manufacturers service documentation, for example in circu\
it diagrams or lists
of components, a symbol is used to indicate that a specific component sh\
all be replaced only
by the component specified in that documentation for safety reasons, the\
following symbol shall
be used:
This product contains certain electrical parts contain chemicals which a\
re known to the State of
California to cause cancer, birth defects or other reproductive harm.
Health & Safety Code Section 25249.6 - Proposition 65
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 h\
ave been trained to properly and safety repair
complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliabi\
lity of the product and may void the warranty.
If you are not qualified to perform the repair of this product properly \
and safety, you should not risk trying to do so
and refer the repair to a qualified service technician.
CAUTION:
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
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
Wave length : 785 nm to 814 nm
Maximum output : 1 190 µW(Emitting period : unlimited)
Additional Laser Caution
Transistors Q101 in PCB drive the laser diodes.
When Q101 is shorted between their terminals, the laser diodes will radiate beam.
If the top cover is removed with no disc loaded while such short-circuit is continued,
the naked eyes may be exposed to the laser beam.
- Safety Precautions for those who Service this Unit.
When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable
results.
Caution:
1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept.
CAUTION
CLASS 1M INVISIBLE LASER RADIATION WHEN OPEN. DO NOT VIEW DIRECTLY WITH \
OPTICAL INSTRUMENTS 2. During repair or tests, do not view laser beam for 10 seconds or longer.
