3. Precaution of Laser Diode

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 from pickup: 100
Laser radiation from pickup unit is safety level, but be sure the
followings:
1. Do not disassemble the pickup unit, since radiation from exposed
laser diode is dangerous.
2. Do not adjust the variable resistor on the pickup unit. It was
