WARNING

This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of

California to cause cancer

Health & Safety Code Section 25249.6 - Proposition 65

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.

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 nm to 660 nm

CD:770 nm to 810 nm

DVD : 2.48 mW(Emitting period :9 sec.)

CD : 705 W(Emitting period : unlimited)

Additional 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.

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.

In addition, be sure that there are no pinched wires, etc.

7 Make sure screws and soldering scraps do not remain inside the product.

Please check that neither solder debris nor screws remain inside the product.

8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.

Damaged power cords may lead to fire accidents, so please be sure that there are no damages.

If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure

connections and suitable usage. Please exchange the power cord if necessary.

0 Safe environment should be secured during servicing.

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
