CAUTION:
THIS PRODUCT UTILIZES A LASER.

USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE

l Precaution of Laser Diode
CAUTION:
Wave length: 780 nm _
Maximum output radiation power from pick up: 100 pWNDE

SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

This product utilizes a laser diode with the unit turned "on, invisible laser radiation is emitted from the pick up lens.

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

1. Do not disassemble the pick up unit, slnce 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 focus lens using optical instruments.
4. Recommend not to lock at pick up lens for a long time.

ACHTUNG:
Wellenlange: 780 nm
Maximale strahlungsleistung der laserinhelt: 100 pWNDE

Dieses produkt enthalt eine laserdiode. Im eingeschalteten zustand wird unsicvhtbare laserstrahlung von der lasereinheit adgestrahit.

Die strahlung an der lasereinheit ist ungefahrllch, wenn tolgende punkte beachtet warden:

1. Die lasereinheit nicht zerlegen, da die strahlung an der freigelegten laserdiode geféhriich ist.
2. Den werksseitigjustierten einstellregler der lasereinreit nichtverstellen.
3. Nicht mit optischen instrumenten in die tokussierlinse blicken.

4. Nicht fiber langere zeit in die tokussierlinse blicken.
