5. Precaution of Laser Diode
Caution :
This product utilizes a laser diode with the unit turned "ON",
invisible laser radiation is emitted from the pick up lens. /
Wavelength : 780 nm / Maximum output radiation power from pick
up : 100
W/VDE / Laser radiation from pick up unit is safety level,
but be sure the followings:
1. Do not disassemble the optical pick up unit, since radiation from
exposed laser diode is dangerous.
2. Do not adjust the variable resistor on the pick up unit. It was
