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

Wavelength: 780 nm
Maximum output radiation power from pick up: 100 uWNDE

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

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

3. Do not look at the focus lens using optical instruments.

4. Recommend not to look at pick up lens for a long time.

ACHTUNG: Dieses produkt enthali sine IaserdiodeI lm eingeschalteten zustand wird unsichtbare laserstrahlung von der lasereinheit abgestrahlt.

Wellenlinge: 780nm
Maximale strehlungslelstung der lasereinheit: 100 uWNDE

Die strahlung an der lasereinheit ist ungelahrlioht wenn folgende punkte beaohtet werden:

tI Die lasereinheit nicht zerlegen, da die strahlung an der freigelegten laserdiode geféhrlich ist.
2. Dan werksseitig justierten einstellregler der Iasereinreit nicht verstellen.

3. Nicht mit optischen insirumenten in die fokussierlinse blicken.

4. Nioht fiber lingere zeit in die tokussierlinse blicken.
