I PRECAUTION OF LASER DIODE

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

Wave length: 780 nm
Maximum output radiation power from pick up: 100 pWNDE

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

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

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

ACHTUNG: Dieses produkt enthéll eine Iaserdiode. lm eingeschalteten zustand wird unsuchtbare laserstrahlung von der lasereinheit abgestrahlt.

Wellenlange: 780 nm
Maximale slrehlungsleislung der lasereinheit: 100 uW/VDE

Die strahlung an der lasereinheit ist ungelahrlich, wenn lolgende punkte beachtet werden:

1. Die Iasereinheit nicht zerlegen, da die strahlung an der lreigelegten Iaserdiode gefahrlich 1st.
2. Den werksseitig iustierten einslellregler der lasereinreit nicht verstellen,

3. Nicht mit optischen instrumenten in die tokussierlinse blicken.

4. Nichl iiber langere zeit in die Iokussierlinse blicken.
