1. Safety Precautions for those who Service this Unit.
· Follow the adjustment steps (see pages 103 through 123)in the service manual when servicing this unit. When check
-
ing 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 13cm from the focus lens must be kept.
2. During repair or tests, do not view laser beam for 10 seconds or longer.
2. The triangular label is attached to the mechanism

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.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacture.
Discord used batteries according to the manufacture's instructions.

124). 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 106).
