I Precaution of Laser Diode

CAUTION:

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.

AGHTUNG: Dieses Produkt enthalt eine Laserdiode. lm elngeschalteten Zustand wird unsichtbare Leserstrahlung von der

Lasereinheit abgestrahlt.

Wellenlange: 780 nm
Maximale Slrahlungsleistung der Lasereinheit: 100 uWNDE

Die Sirahlung an der Lasereinhelt ist ungetahrlich, wenn lolgende Punkte beachtet werden:

1. Die Lasereinheit nicht zerlegen, da die Strahlung an der freigelegten Laserdiode geféihrlich ist.
2. Den werkseitig justierten Einslellregler cler Lasereinhit nicht verstellen.

3. Nicht mit optischen lnstrumenten in die Fokussierlines blicken.

4. Nicht fiber langere Zeit in die Fokussierlines blicken.
