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

Maximum output radiation power from pickup: 100uW/VDE

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.

. Do not adjust the variable resistor on the pickup unit.

It was already adjusted.

ACHTUNG:

2
3. Do not look at the focus lens using optical instruments.
4

. Recommend not to look at pickup lens for a long time.

Dieses Produkt enthalt eine Laserdiode.

Im eingeschalteten Zustand wird unsichtbare Laser~

strahlung von der Laserelnheit abgestrahlt.

Wellenlange: 780nm

Maximale Slrahlungslelstung der Lasereinheit: 1DDuWIVDE

Die Strahlung an der Lasereinheit lst ungeffihrlich, wenn folgende Punkte beachtet werden:

1. Die Lasereinheit nicht zerlegen, da die Strahlung an der frelgeiegten Laserdiode gefithrlich ist.
2. Den werkseitlg justierlen Einstellregler der Lasereinheit nichl verstellen.

3. Nicht mit optischen lnstrumenten in die Fokussierlinse blicken.

4. Nicht fiber Iangere Zeit in die Fokussierlinse blioken.
