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
DVD : 2.48mw(Emitting period :9sec. )
CD : 705µw(Emitting period : unlimited)
Additionla Laser Caution
Transistors Q1101 and Q1102 in PCB drive the laser diodes for DVD and CD
respectively. When Q1101 or Q1102 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.
RI RC
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.

After completing repair of this product, please confirm that the fan motor (center) is rotating.
Check Method
1. DVD video is played with this product.
2. The operation is normal if the operation noise (pulse) can be observed after connecting oscilloscope to TP781
located at the bottom of this product. Under this circumstance, be careful not to contact TP781 with chassis as
the power fuse of fan motor (center) will blow out, disabling the fan motor (center) to rotate.
-Operation Check of Fan Motor (Center)
-Inverter for LCD back light becomes a high voltage.
-Service Precaution
1. You should conform to the regulations governing the
product (safety, radio and noise, and other regulations),
and should keep the safety during servicing by following
the safety instructions described in this manual.
2. Before disassembling the unit, be sure to turn off
the power. Unplugging and plugging the connectors
during power-on mode may damage the ICs inside
the unit.
3. To protect the pickup unit from electrostatic discharge
during servicing, take an appropriate treatment
(shorting-solder) .
4. After replacing the pickup unit, be sure to skew
adjustment.
5. During disassembly, be sure to turn the power off since
an internal IC might be destroyed when a connector
is plugged or unplugged.
