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

Maximum output radiation power from pickup: 100 uWNDE

Laser radiation lrom the pickup lens is salety 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 eingeschalteten Zustand wird unsichtbare Leserstrahlung von der

Lasereinheit abgestrahlt.
Wellenlainge: 780 nm

Maximale Strahlungsleistung der Lasereinheit: 100 WNDE

Die Strahlung an der Lasereinheit ist ungefahriich, wenn tolgende Punkte beachtet werden:

1. Die Lasereinheit nicht zerlegen, da die Strahlung an der ireigelegten Laserdiode getahrlich ist.
2. Den werkseitig justierten Einstellregler der Lasereinhit nicht verstellen.

3. Nicht mit optischen Instrumenten in die Fokussierlines blicken.

4. Nicht iiber langere Zeit in die Fokussierlines blicken.
