Laser Beam Safety Precautions
This Blu-Ray player uses a pickup that emits a laser beam.
The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep
your eyes at least 30 cm away from the pickup lens when the diode is turned on. Do not look directly at the laser
beam.
CAUTION: Use of controls and adjustments, or doing procedures other than those specified herein, may result in
hazardous radiation exposure.
Location: Inside Top of Blu-Ray mechanism.
Do not look directly at the laser beam coming
from the pickup or allow it to strike against your
skin.
