Sony CDP-470 - Laser Beam Safety Precautions During Servicing

CDP-270/470
SERVICING NOTE
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs a laser. Therefore, be sure to fol- 1. Laser Diode Properties
low carefully the instructions below when servicing. ® Material: GaAlAs
@® Wavelength: 780 nm
@ Emission Duration: continuous
@ Laser Output: max. 44.6 uW*
* This output is the value measured at a distance of
about 200 mm from the objective lens surface on
the Optical Pick-up Block.
CAUTION
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous radiation exposure.
2. During service, do not take the Optical Pick-up
NOTES ON HANDLING THE OPTICAL PICK- ae aDatES and eo mot adjust he BEC inet,
UP BLOCK OR BASE UNIT I there is a breakdown in the APC circuit (includ-
ing laser diode), replace the entire Optiocal Pick-
up Block (including APC borad).
The laser diode in the optical pick-up block may
suffer electrostatic breakdown because of the poten-
tial difference generated by the charged electrostatic
load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-
down and also use the procedure in the printed
matter which is included in the repair parts.
The flexible board is easily damaged and should be
handled with care.
