IPRECAUTION OF LASER DIODE

CAUTION:

ACHTUNG:

ADVARSEL:

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

Wave length: 780nm

Maximum output radiation power from pickup: 100uW/VDE

Laser radiation from the pickup lens is safety level, but be sure the followings:

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.

Do not look at the focus lens using optical instruments.

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

99°F?

Dieses Produkt enthalt eine Laserdiode. lm eingeschalteten Zustand wird unsichtbare Laserstrahlung
von der Lasereinheit abgestrahlt.

Wellenlange: 780nm
Maximale Strahlungsleistung der Lasereinheit: 100uW/VDE

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

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

Nicht mit optischen Instrumenten in die Fokussierlines blicken.

Nicht fiber langere Zeit in die Fokussierlinse blicken.
