SERVICE PROCEDURES-1
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
PRECAUTIONS
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 PICKUP BLOCK.

1. Ground for the work-desk.
Place a conductive sheet such as a sheet of copper
(with impedance lower than 10 Mohm) on the work-
desk and place the set on the conductive sheet so that
the chassis can be grounded.
2. Grounding for the test equipments and tools.
Test equipments and toolings should be grounded in
order that their ground level is the same the ground of
the power source.
3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.
4. Select a soldering iron that permits no leakage and
have the tip of the iron well-grounded.
5. Do not check the laser diode terminals with the
probe of a circuit tester or oscilloscope.
DANGER:
INVISIBLE LASER RADIATION WHEN OPEN AND
INTERLOCK FAILED OR DEFEATED. AVOID DIRECT
EXPOSURE TO BEAM.
CAUTION:
HAZARDOUS LASER AND ELECTROMAGNETIC
RADIATION WHEN OPEN AND INTERLOCK DEFEATED.
ATTENTION:
RAYONNEMENT LASER ET ELECTROMAGNETIQUE
DANGEREUX SI OUVERT AVEC L'ECLENCHEMENT
DE SECURITE ANNULE.
