2. For pickup unit(service)(CXX1530) handling, please refer to"Disassembly"(see page 143).
During replacement, handling precautions shall be taken to prevent an electrostatic discharge(set the short switch
of the pickup unit to the SHORT side).
3. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is
plugged or unplugged.
4. Please adjusting the skew after changing the pickup unit(see page 118).

LASER PRODUCT
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:
DVD:640~660nm
CD:770~810nm
Maximum output:2.44mw(Emitting period :9sec.)
DVD:743mw(Emitting period : unlimited)
Additionla Laser Caution
Transistors Q1104 and Q1108 in PCB drive the laser diodes for DVD and CD
respectively. When Q1104 or Q1108 is shorted between their terminals,
the laser diodes for DVD or CD 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.
