This service manual

is intended for qualified service technicians; it is not

meant for the casual do-it-yourselfer. Qualified technicians have the neces-

sary 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

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

AC 60Hz outlet and turn the AC power switch on. Any

current measured must not exceed 0.5mA.

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 replacernent component which

dose not have the same safety characteristics as the

PIONEER recommended replacement one, shown in

the parts list in this Service Manua!, 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 consw't the current

PIONEER Service Manual.

ditional copies of, PIONEER Service Manual may be
