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.

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.
