SAFETY

NOTICE

Many

electrical

and

mechanical

parts

in

the

appli-

ance

have

special

safety

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
