CAUTION:
THIS PRODUCT UTILIZES A LASER.

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

I Precaution of Laser Diode

CAUTION:
Wave length: 780 nm

Maximum output radiation power from pick up: 100 uW/VDE

Laser radiation from the pick up unit is safety level, but be sure the followings:

1 Do not disassemble the pick up unit, since radiation from exposed laser diode is dangerous,
2. Do not adjust the variable resistor on the pick up unit It was already adjusted.

3. Do not lock at the locus lens using optical Instruments
4. Recommend not to lock at pick up lens for a long time.
