and refer the repair to a qualified service technician.

1. Safety Precautions for those who Service this Unit.

Follow the adjustment steps 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 13 cm 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.

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

Maximum Output

ave length:

DVD:660 nm to 670 nm

CD:780 nm to 800 nm

DVD : 1.27 mW(Emitting period :9 sec.)

CD : 6.26 mW(Emitting period : unlimited)

Additional Laser Caution

Transistors Q1103 and Q1104 in PCB drive the laser diodes for DVD and CD

respectively. When Q1103 or Q1104 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.
