1. Safety Precautions for those who Service this Unit.

· Follow the adjustment steps (see pages 80 through 100)in the service manual when servicing 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 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.

- DVD Player Service Precautions

1. Never adjust the LD VR in the pickup unit to protect the pickup from electrical damages.

2. For pickup unit(service)(CXX1530) handling, please refer to"Disassembly"(see page 109).

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 83).

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.
