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 repalr 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

Lead in solder used in this product Is listed by the California Health and Welfare agency as a known reproductive toxicant which

may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).

When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with

the solder. Also, when soldering do not inhale any smoke or fumes produced.

NOTICE

(FOR CANADIAN MODEL ONLY)

Fuse symbols -HE—# (fast operating fuse) and/or -§E—8 (slow operating fuse) on PCB indicate that replacement parts

must be of identical designation.

REMARQUE

(POUR MODELE CANADIEN SEULEMENT)

Les symboles de fusible -BE—H (fusible de type rapide) et/ou -§&—# (fusible de type lent) sur CCI indiquent que Jes

piéces de remplacement doivent avoir la méme désignation.

(FOR USA MODEL ONLY)

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

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.

Reading should

Leakage | "Ot be above

0.5mA

Test all

exposed metal

surfaces

Also test with

plug reversed

(Using AC adapter plug as required)

Earth

ground

AC Leakage Test

equivalent between the earth ground and ail exposed |

ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED ABOVE ARE INDICATIVE OF A PO- TENTIAL SHOCK HAZARD AND MUST BE COR-

RECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

2.PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appli-

ance have special safety related characteristics. These

are often not evident from visual inspection nor the

protection afforded by them necessarily can be ob-

tained by using replacement components rated for vol-

tage, 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 A on the schematics and

on the parts list in this Service Manual.

The use of a substitute replacement component which

dose 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 ad-

ditional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

Additional Laser Caution

1. Laser Interlock Mechanism

The ON/OFF status of the clamp switch ($1005) for

detecting loading completion is detected by the system

microprocessor, and the design prevents laser diode

oscillation when the clamp switch is OFF.

Thus, the interlock will no longer function if the clamp

switch (S1005) is deliberately shorted.

The interlock also does not function in the test mode *1.

Laser diode oscillation will continue, if between collector

and emitter of Q102 and Q110 mounted on the HAMP

UNIT is connected to GND, shorted to each other ( fault

condition ).

If the fault condition described in 1 is induced with the

cover removed and the objective lens extending past the

outer circumference of the disc clamper diameter, close

viewing of the objective lens with the naked eye will

cause exposure to a Class 1 or higher laser beam.

2. EXPLODED VIEWS, PACKING AND PARTS LIST NOTES:

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

@ The A\ 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.

© Parts marked by “@ ” are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.

4. PCB PARTS LIST NOTES: @ Parts marked by “NSP” are generally unavailable because they are not in our Master Spare Parts List.

DW -S114X

@ The A, 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.

@ Parts marked by“ @® ” are not always kept in stock. Their delivery time may be longer than usual or they may be unavailable.

@ When ordering resistors, first convert resistance values into code form as shown in the following examples.

Ex.1 When there are 2 effective digits(any digit apart from 0), such as 560 ohm and 47k ohm(tolerance is shown by J=5%, and K= 10%). 560 CQ > 56 X [Oo em SO] ccecececeeeeeeeeeeeeeeeeeeeeseeeseesesenseseseeees RDU8PMB\6I J
