Wave length : 780 nm
Maximum output radiation power from pick up : 100 pWNDE

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

Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous.
Do not adjust the variable resistor on the pickup unit. It was already adjusted.
