The following

check should l)e

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

linput/output

terminals,

screwheads,

metal

overlays,

control shaft, etc.). Plug

the

AC Iine

cord ol the

appliance directly inro

a

1 20V

AC

6OHz

outlet

and turn

the

AC

power

switch on.

Any

current

measured

must not

exceed

O.5mA.

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 soecial safetv 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 specaal safety characteristics are identified in

this Service Manual.

Elect.ical

components

having

such features are

identilied

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 reDlacement

one.

shown in

the

parts

list in this Service

Manual, may

create shock,

fire,

or other

hazards.

Product Safety is conlinuously

under

review

and

CD MECHA ASSY DIAGNOSIS AND REPLACEMENT

1. Remove the cover.

2. OPEN the tray and lift

the

tray

cap,

pulling

the bottom of the tray cap toward

you.

After removing the

tray

cap,

CLOSE the tray.

3. Remove the VOL knob and 2 screws

(BBZ30P080FZK)

holding the VR

assy in

place.

4. Remove the 3 screws between the front

Danel and

the chassis.

6. Remove the front

panel

from the chassis

(watching

out for the claw on the left

and right), and open the side of

the AF

CD

assy.

(Refer

to

Fig. 1)

NOTE:

Do not remove the rear

panel

and AF CD assy at this time.

Under

these conditions most of the PCB diagnosis

and

parts

replacement can be

performed.

REMOVAL OF AF CD ASSY

1. Under the conditions of the

previous paragraph,

remove the

rear

panel

and A-F CD assy.

(Do

not separate the rear

panel

and
