This product utilizes a laser diode with the unit turned "on", invisible laser radiation is emitted lrom the pick up lens.

Maximum output radiation power tram pick up: 100 uW/VDE

Laser radiation lrom the pick up lens is salety level. but be sure the lollowings:

1. Do not disassemble the optical pick up unit. since radiation lrom exposed laserd diode is dangerous.
2. Do not adjust the variable resistor on the pickup unit It was already adjusted.

3. Do not look at the locus lens using optical instruments.

4. Recommend not to look at pick up lens tor a long time.

ACHTUNG:
Iasereinhelt abgestrahlt.

Wellenlénge: 780 nm
