SAFETY INFORMATION
CAUTION: The use of optical instruments with this
product will increase eye hazard.
Invisible laser radiation is emitted from the optical
pickup lens when the unit is turned on.
1. Do not look directly into the pickup lens.
2. Do not use optical instruments to look at the pickup
lens.
3. Do not adjust the preset variable resistor on the
optical pickup.
4. Do not disassemble the optical pickup unit.
5. Use of controls or adjustment or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
6. Replace optical pickup only with manufacturers
specified type.
Laser output: 0.65mW
Wavelength: 665nm
This product utilizes an embedded class 2 laser (CFR).
