EW
1. Safety Precautions for those who Service this Unit.
• Follow the adjustment steps (see pages 143 through 156)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
unit frame.

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
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.

Battery
Slide the tray out on the back of the
remote controller and insert the battery
with the (+) and (–) poles pointing in
the proper direction.
Note :
• Use a CR2025 (3V) lithium battery
only. Never use other types of battery
with this unit.
1. In the state of FAN being attached to the mother unit, the voltage of about 6 to 8 V is impressed between TEST
point (FAN1) on surface A of the base plate and adequate GND to confirm its operation by visual observation.
2. After product assembly, a waveform observation is conducted using oscilloscope while playing DVD on TEST
point (TEST1) in front of chassis hole on lower face and adequate GND to confirm the existence of operation
noise (pulse) shape.
-Method of FAN Operation Confirmation
-Inverter for LCD back light becomes a high voltage.
