1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it-

yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained

to properly and safely repair complex products such as those covered by this manual.

Improperly performed repairs can adversely affect the safety and reliability of the product and may

void the warranty. If you are not qualified to perform the repair of this product properly and safely, you

should not risk trying to do so and refer the repair to a qualified service technician.

WARNING

This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause

cancer, birth defects or other reproductive harm.

Health & Safety Code Section 25249.6 Proposition 65

NOTICE

(FOR CANADIAN MODEL ONLY)

Fuse symbols

(fast operating fuse) and/or

(slow operating fuse) on PCB indicate that replacement parts must

be of identical designation.

REMARQUE

(POUR MODÈLE CANADIEN SEULEMENT)

Les symboles de fusible

(fusible de type rapide) et/ou

(fusible de type lent) sur CCI indiquent que les pièces

de remplacement doivent avoir la même désignation.

ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL

SHOCK HAZARD AND MUST BE CORRECTED BEFORE

RETURNING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance

have special safety related characteristics. These are

often not evident from visual inspection nor the protection

afforded by them necessarily can be obtained by using

replacement components rated for voltage, wattage, etc.

Replacement parts which have these special safety

characteristics are identified in this Service Manual.

Electrical components having such features are identified

by marking with a

on the schematics and on the parts list

in this Service Manual.

The use of a substitute replacement component which does

not have the same safety characteristics as the PIONEER

recommended replacement one, shown in the parts list in

this Service Manual, may create shock, fire, or other hazards.

Product Safety is continuously under review and new

instructions are issued from time to time. For the latest

information, always consult the current PIONEER Service

Manual. A subscription to, or additional copies of, PIONEER

Service Manual may be obtained at a nominal charge from

PIONEER.

1. SAFETY PRECAUTIONS

The following check should be performed for the

continued protection of the customer and service

technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water

pipe, conduit, etc.) by connecting a leakage current tester

such as Simpson Model 229-2 or equivalent between the

earth ground and all exposed metal parts of the appliance

(input/output terminals, screwheads, metal overlays, control

shaft, etc.). Plug the AC line cord of the appliance directly

into a 120V AC 60Hz outlet and turn the AC power switch

on. Any current measured must not exceed 0.5mA.

(FOR USA MODEL ONLY)

VORSICHT!

1. Laser Interlock Mechanism

The position of the switch (S601) on the SERVO

MECHANISM Assy for detecting loading state is detected

by the system microprocessor, and the design prevents

laser diode oscillation when the switch (S601) is not on

CLMP terminal side (CLMP signal is OFF or high level.).

Thus, the interlock will no longer function if the switch

(S601) is deliberately set to CLMP terminal side (low

level).

The interlock also does not function in the test mode

.

Laser diode oscillation will continue, if pin 1 of M51593FP

(IC101) on the PRE-AMP BOARD ASSY mounted on the

CD-R PICKUP is connected to GND, or pin 19 is

connected to low level (ON), or else the terminals of Q101

are shorted to each other (fault condition).

2. When the cover is opened with the servo mechanism

block removed and turned over, close viewing of the

objective lens with the naked eye will cause exposure to a

Class 1 laser beam.

Additional Laser Caution

Refer to page 51.

2. EXPLODED VIEWS AND PARTS LIST

NOTES :

Parts marked by " NSP " are generally unavailable because they are not in our Master Spare Parts List.

The

mark found on some component parts indicates the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of identical designation.

Screw adjacent to

mark on the product are used for disassembly.
