Precaution of Laser Diode
[For (P,PC) areas only]

CAUTION: This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens when the unit is

turned on:
Do not look directly into the pickup lens.

WQPPN.

hazardous radiation exposure.

[For (EB, EC, 60, GN) areas only]

Do not use optical instruments to look at the pickup lens.

Do not adjust the preset variable resistor on the optical pickup.

Do not disassemble the optical pickup unit.

It the optical pickup is replaced, use the manuiactures specified replacement pickup only.

Use of control or adjustments or performance oi procedures other than those specified herin may result in

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 trom pickup: 100 pWNDE

Laser radiation from the pickup lens is saiety 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 iocus lens using optical instruments.
4. Recommend not to look at pickup lens tor a long time.

ACHTUNG: Disses Produkt enthalt eine Laserdiode. lm eingeshalteten Zustand wird unsichlbare Leserstrahlung von der
Lasereinheit abgestrahlt.

Wellenlange: 780 nm
Maximale Strahlungsleistung der Lasereinheit: 100 pWNDE

Die Strahlung an der Lasereinheit ist ungeiahrlich, 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 fiber tangere Zeit in die Fokussieriines blicken.

ADVARSEL: I dette a apparat anvendes laser.
