SAFTY 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.

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.

ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED

ABOVE

ARE

INDICATIVE

POTENTIAL

SHOCK

HAZARD

AND

MUST

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. Laser Interlock Mechanism

The position of the switch (S510) for detecting loading completion

is detected by the system microprocessor, and the design prevents

laser diode oscillation when the switch is not in LPS1 terminal side

(when the mechanism is not clamped and LPS1 signal is high level.)

Thus, the interlock will no longer function if the switch is deliberately

set to LPS1 terminal side. ( if LPS1 signal is low level ).

In the test mode* the interlock mechanism will not function.

Laser diode oscillation will continue, if pin 4 of AN8702NFH (IC800)

on the CDPB ASSY is connected to GND, or else the terminals of

Q600 are shorted to each other (fault condition).

2. When the cover is opened, close viewing of the objective

lens with the naked eye will cause exposure to a Class 1 laser beam.

Additional Laser Caution

* Refer to pages 71.
