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

Maximum output radiation power from pickup: 100pW/VDE

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

PPN.

AGHTUNG: Dieses Produkt enthalt eine Laserdiode.

von der Lasereinheit abgestrahlt.
Wellenlénge: 780nm

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.
