SAFETY-RELATED COMPONENT
WARNING!!
THE MARK FOUND ON SOME COMPONENT
PARTS INDICATES THE CRITICAL FOR RISK OF
FIRE AND ELECTRIC SHOCK.
WHEN REPLACING, BE SURE TO USE PARTS OF
IDENTICAL DESIGNATION.
MAKE LEAKAGE-CURRENT OR RESISTANCE
MEASUREMENTS TO DETERMINE THAT EXPOSED
PARTS ARE ACCEPTABLY INSULATED FROM THE
SUPPLY CIRCUIT BEFORE RETURNING THE
APPLIANCE TO THE CUSTOMER.

DPC-5.2
SERVICE NOTE
1. Replacing the fuses 2. Safety-check out
(Only U.S.A. model)
After correcting the original service problem perform the
following safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10M ohm at 500V
REF.NO. PART NO. DESCRIPTION
F1 252159 2A-UL/T-237
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse , For fuse rating, refer to
the marking adjust to the symbol.
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.
TO REDUCETHE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSETHIS APPLIANCETO RAIN
OR MOISTURE. DANGEROUS HIGHVOLTAGES ARE PRESENT INSIDETHE ENCLOSURE. DO NOT OPENTHE
CABINET. REFER SERVICING TO QUALIFIED PERSONNEL ONLY.
TO PREVENT ELECTRIC SHOCK, MATCHWIDE BLADE OF PLUGTOWIDE SLOT, FULLY INSERT.
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.
WARNING :
CAUTION :
ATTENTION :
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.
1. Ground for the work-desk.
Place a conductive sheet such as a sheet of copper (with impedance lower than 10Mohm) 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.
PRECAUTIONS
LASER CAUTION
Initialization of setup
1. Press the "DISC 4" and "CDPLAY" key to the same timing.
The "DISC 4 key is pushed previously.
Then, light off the FL tube.
2. Push the power switch.
