SERVICE PROCEDURE
PRECAUTIONS
1. Ground for the work-desk.
Place a conductive sheet such as a sheet of copper (with impedance lower than 10M ohm) on the work-desk and
place the set on the conductive sheet so that the chassis.
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.
1. Replacing the fuses 2. Safety-check out
(Only U.S.A. model)
This symbol located near the fuse indicates that the After correcting the original service problem perform the
fuse used is show operating type, For continued protection against following safety check before releasing the set to the customer
fire hazard, replace with same type fuse , For fuse rating, refer to Connect the insulating-resistance tester between the plug of
the marking adjust to the symbol. power supply cord and terminal GND on the back panel.
Specifications: More than 10M ohm at 500V
Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.

LASER CAUTION
The lightning flash with arrowhead symbol, within an equilateral triangle, is
intended to alert the user to the presence of uninsulated "dangerous voltage"
within the product's enclosure that may be of sufficient magnitude to constitute
a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user
to the presence of important operating and maintenance (servicing) instruction
in the literature accompanying the appliance.
WARNING : TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN
OR MOISTURE. DANGEROUS HIGH VOLTAGES ARE PRESENT INSIDE THE ENCLOSURE. DO NOT OPEN THE
CABINET. REFER SERVICING TO QUALIFIED PERSONNEL ONLY.
CAUTION : TO PREVENT ELECTRIC SHOCK, MATCH WIDE BLADE OF PLUG TO WIDE SLOT, FULLY INSERT.
ATTENTION : POUR EVITER LES CHOCS ELECTRIQUE, INTRODUIRE LA LAME LA PLUS LARGE DA LA FICHE DANS LA
BORNE CORRESPONDANTE DA LA PRISE ET POUSSER JUSQU' AU FOND.
Initialization of setup
1. Press the "CD PLAY" and "DISC 3" key to the same timing on the front panel.
You will see that the program is updated by watching the version in the FL tube.
2. Push the power switch.
