PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
VAROITUS!
Laiteen Käyttäminen muulla kuin tässäkäyttöohjeessa mainit-
ulla tavalla saattaa altistaa käyt-täjän turvallisuusluokan 1 ylit-
tävälle näkymättömälle lasersäteilylle.
VARNING!
Om apparaten används påannat sätt än vad som specificeras i
denna bruksanvising, kan användaren utsättas för osynling
laserstrålning, som överskrider gränsen för laserklass 1.
Caution: Invisible laser radiation when
open and interlocks defeated avoid expo-
sure to beam.
Advarsel:Usynling laserståling ved åbning,
når sikkerhedsafbrydere er ude af funktion.
Undgåudsættelse for stråling.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
ATTENTION
L'utilisation de commandes, réglages ou procédures autres que
ceux spécifiés peut entraîner une dangereuse exposition aux
radiations.
ADVARSEL!
Usynlig laserståling ved åbning, når sikkerhedsafbrydereer ude
af funktion. Undgåudsættelse for stråling.
This Compact Disc player is classified as a CLASS 1 LASER
product.
The CLASS 1 LASER PRODUCT label is located on the rear
exterior.
This set employs laser. Therefore, be sure to follow carefully the
instructions below when servicing.
WARNING!
WHEN SERVICING, 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.

Optical Pickup Block and Base Unit Handling Precautions
(LCX-4R)
The laser diode inside the optical pickup can be destroyed by
static electricity due to the static charge accumulated in human
body or in cloths.
Before starting the repair work of optical block and/or laser
diode, be very careful of the electrostatic breakdown because of
potential static electricity from clothing and your body. Follow the
same work procedures that are described in the printed material
supplied with the repair optical block. Also, the FLEX C.B can be
easily damaged. Be very careful when handling it.
Precaution when laser diode is emitting laser
NEVER LOOK into the laser diode from directly on top of the
laser diode. Doing so may result in loss of eyesight.
Precaution when handling the optical pickup (LCX-4R)
Because the laser diode inside the optical pickup can be very
easily destroyed by static electricity, short circuit the laser
taps of the FLEX C.B by solder-bridge before starting
handling the optical laser. At the same time, take the
sufficient preventive measures to protect the laser diode from
the static electricity. The FLEX C.B can be easily damaged.
Be very careful when handling it.
•If the MAIN C.B is removed when this machine is powered
on during repair, this machine will not work. Fix the protruded
portion ( portion) of the OPEN/CLOSE detection switch
(MAIN C.B S806) with adhesive tape in order to work this
machine.
•The FLEX C.B (Overwrite head) is connected to the MAIN
C.B directly by soldering. Be careful not to damage the FLEX
C.B (Overwrite head).
To perform any repair work on the component side of the
MAIN C.B, connect the FLEX C.B (Overwrite head) and the
MAIN C.B with the jumper leads before starting the repair
work. (Refer to DISASSEMBLY INSTRUCTIONS on page 9.)
* For replacement and repair of CDX2671-203 GA (IC801) that
is used in this machine, special tool is required.

Service Note
•The sets that use the microprocessor version 1.000
are adjusted of their setup data by the MANUAL mode
in the factory before shipment. If the NV reset is
executed in these sets, the setup data will be cleared.
If the NV reset is executed in the sets of version 1.000,
change the adjustment value in accordance with the
adjustment value change procedure immediately after
the NV reset is executed. (Refer to ELECTRICAL
ADJUSTMENT page 32.)
•If non-volatile memory of this machine is replaced, the
program correction data must be written in the non-
volatile memory. After the non-volatile memory is
replaced, write the appropriate correction data that suit
to the version number of the microprocessor in
accordance with the patch data re-writing procedure
when the non-volatile memory is replaced. (Refer to
ELECTRICAL ADJUSTMENT page 37.)
