PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs a laser. Therefore, be sure to follow carefully
the instructions below when servicing.
WARNING!!
SERVICE WARNING : DO NOT APPROACH THE
LASER EXIT WITH THE EYE TOO CLOSELY.
IN CASE IT IS NECESSARY TO CONFIRM LASER
BEAM EMISSION, BE SURE TO OBSERVE FROM
A DISTANCE OF MORE THAN 30cm FROM THE
SURFACE OF THE OBJECTIVE LENS ON THE
OPTICAL PICK-UP BLOCK.
Laser Diode Properties
Material: GaAS/GaALAs
Wavelength: 790nm
Emission Duration: continuous
Laser output: max. 0.5mW*
*This output is the value measured at a distance about 1.8mm
from the objective lens surface on the Optical Pick-up Block.
