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

Wave length: 780 nm

Maximum output radiation power from pickup: 100 uWNDE

Laser radiation from the pickup lens is safety level, but be sure the followings:
1. Do not disassemble the optical pickup unit. since radiation from exposed laser 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 pickup lens for a long time.
ACHTUNG:

Dieses Produkt enthalt eine Laserdiode. lm elngeschalteten Zustand wlrd unsichtbare Leseretrahlung von der Lasereinhelt

abgesirahlt.
Wellenlage: 780 nm

Maximale Strahlungsleistung der Lasereinheit: 100 pW/VDE

Die Strahlung an der Lasereinheit ist ungefahrlich. wenn folgende Punkte beachtet werden:

1. Die Lasereinheit nicht zerlegen, da die Sirahlung an der freigelegten Laserdiode gefahriich ist.
2. Den werkseitig justierten Einstellregler der Lasereinhit nicht verstellen.

3. Nicht mit optischen lnstrumenten in die Fokussierlines blicken.

4. Nicht uber langere Zeit in die Fokussierlines blicken.
