SECTION 1
PRECAUTION
1.1 Safety Precautions
(1) This design of this product contains special hardware and
many circuits and components specially for safety purpos-
es. For continued protection, no changes should be made
to the original design unless authorized in writing by the
manufacturer. Replacement parts must be identical to
those used in the original circuits. Services should be per-
formed by qualified personnel only.
(2) Alterations of the design or circuitry of the product should
not be made. Any design alterations of the product should
not be made. Any design alterations or additions will void
the manufacturers warranty and will further relieve the
manufacture of responsibility for personal injury or property
damage resulting therefrom.
(3) Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteris-
tics are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by us-
ing replacement components rated for higher voltage, watt-
age, etc. Replacement parts which have these special
safety characteristics are identified in the Parts List of Ser-
vice Manual. Electrical components having such features
are identified by shading on the schematics and by ( ) on
the Parts List in the Service Manual. The use of a substitute
replacement which does not have the same safety charac-
teristics as the recommended replacement parts shown in
the Parts List of Service Manual may create shock, fire, or
other hazards.
(4) The leads in the products are routed and dressed with ties,
clamps, tubings, barriers and the like to be separated from
live parts, high temperature parts, moving parts and/or
sharp edges for the prevention of electric shock and fire
hazard. When service is required, the original lead routing
and dress should be observed, and it should be confirmed
that they have been returned to normal, after reassem-
bling.
1.2 Warning
(1) This equipment has been designed and manufactured to
meet international safety standards.
(2) It is the legal responsibility of the repairer to ensure that
these safety standards are maintained.
(3) Repairs must be made in accordance with the relevant
safety standards.
(4) It is essential that safety critical components are replaced
by approved parts.
(5) If mains voltage selector is provided, check setting for local
voltage.
1.3 Caution
Burrs formed during molding may be left over on some parts
of the chassis.
Therefore, pay attention to such burrs in the case of pre-
forming repair of this system.
1.4 Critical parts for safety
In regard with component parts appearing on the silk-screen
printed side (parts side) of the PWB diagrams, the parts that are
printed over with black such as the resistor ( ), diode ( )
and ICP ( ) or identified by the " " mark nearby are critical
for safety. When replacing them, be sure to use the parts of the
same type and rating as specified by the manufacturer.
(This regulation dose not Except the J and C version)
1.5 Remote control
The Lithium battery is in danger of explosion if replaced incor-
rectly. Replace it only with the same or equivalent type.
1.6 Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electric-
ity stored in the body, fabric, etc. is discharged, can destroy the
laser diode in the traverse unit (optical pickup). Take care to pre-
vent this when performing repairs.
1.6.1 Grounding to prevent damage by static electricity
Static electricity in the work area can destroy the optical pickup
(laser diode) in devices such as laser products.
Be careful to use proper grounding in the area where repairs are
being performed.
(1) Ground the workbench
Ground the workbench by laying conductive material (such
as a conductive sheet) or an iron plate over it before plac-
ing the traverse unit (optical pickup) on it.
(2) Ground yourself
Use an anti-static wrist strap to release any static electricity
built up in your body.
(3) Handling the optical pickup
• In order to maintain quality during transport and before
installation, both sides of the laser diode on the replace-
ment optical pickup are shorted. After replacement, re-
turn the shorted parts to their original condition.
(Refer to the text.)
• Do not use a tester to check the condition of the laser di-
ode in the optical pickup. The tester's internal power
source can easily destroy the laser diode.

(No.MA596<Rev.005>)6/28
1.7 Handling the traverse unit (optical pickup)
(1) Do not subject the traverse unit (optical pickup) to strong
shocks, as it is a sensitive, complex unit.
(2) Cut off the shorted part of the flexible cable using nippers,
etc. after replacing the optical pickup. For specific details,
refer to the replacement procedure in the text. Remove the
anti-static pin when replacing the traverse unit. Be careful
not to take too long a time when attaching it to the connec-
tor.
(3) Handle the flexible cable carefully as it may break when
subjected to strong force.
(4) I t is not possible to adjust the semi-fixed resistor that ad-
justs the laser power. Do not turn it.
1.8 Attention when traverse unit is decomposed
*Please refer to "Disassembly method" in the text for the
pickup unit.
• Apply solder to the short land sections before the card wire is
disconnected from the connector on the servo board. (If the
card wire is disconnected without applying solder, the pickup
may be destroyed by static electricity.)
• In the assembly, be sure to remove solder from the short land
sections after connecting the card wire.
1.9 Important for laser products
SOLDER
1.CLASS 1 LASER PRODUCT
2.CAUTION :
(For U.S.A.) Visible and/or invisible class II laser radiation
when open. Do not stare into beam.
(Others) Visible and/or invisible class 1M laser radiation
when open. Do not view directly with optical instruments.
3.CAUTION : Visible and/or invisible laser radiation when
open and inter lock failed or defeated. Avoid direct
exposure to beam.
4.CAUTION : This laser product uses visible and/or invisible
laser radiation and is equipped with safety switches which
prevent emission of radiation when the drawer is open and
the safety interlocks have failed or are defeated. It is
dangerous to defeat the safety switches.
5.CAUTION : If safety switches malfunction, the laser is able
to function.
6.CAUTION : Use of controls, adjustments or performance of
procedures other than those specified here in may result in
hazardous radiation exposure.
!Please use enough caution not to
see the beam directly or touch it
in case of an adjustment or operation
check.

SPECIFIC SERVICE INSTRUCTIONS
2.1 How to repair a fuse pattern
2.1.1 Purpose of fuse pattern
In order to prevent serious damage on the circuit, fuse pattern is prepared on the GND line of RCA Terminal. This damage may
take due to improper part replacement with a external equipment via RCA line.
2.1.2 Repair Procedure
(1) Check the shorted circuit at the meltdown point.
Need to clean up if the shorted circuit or carbonization happen at the fuse pattern.
(2) Add following part on the fuse pattern.
(3) Check output level.
2.1.3 After finished repair
Due to improper part replacement, this meltdown occurs.
Thus please notice following information when the unit is returned to your customer.
Things to be checked before installing the unit.
(1) Check the GND line of external amplifier or other equipment which must connect properly.
(2) Check whether the GND line is not short-circuited with the battery terminal. (do not short-circuit these lines)
