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 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 any smoke or fumes produced.

NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts
must be of identical designation.

REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les
pièces de remplacement doivent avoir la même 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
equivalent between the earth ground and all exposed

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 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.

Reading should
not be above

0.5 mA

Earth ground

Device
under
test

Also test with plug
reversed
(Using AC adapter
plug as required)

Leakage

current

tester

Test all exposed
metal surfaces

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO­TENTIAL SHOCK HAZARD AND MUST BE COR­RECTED BEFORE RETURNING THE APPLIANCE
TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appli­ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob­tained by using replacement components rated for
voltage, 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
on the parts list in this Service Manual.
The use of a substitute replacement component which
does 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 ad­ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

NOTE!

Without drive power from the AC adapter or
from batteries, the top cover of this unit can
not be opened.
Do not force the top cover open while the disc
is spinning.

To realize a high transfer rate, the disc in this unit
spins at high speed.
If the top cover is opened while the disc is spinning,
the disc may be thrown out. So, do not open the
top cover while the disc is spinning.

This mode is selected when the power is switched on
with use of the AC adapter. When the vibrations or the
spinning noises appear large, press the MODE button
once to switch to the PS mode shown below.

[PS mode: -

The data transfer rate is equivalent to 4.4x speed at the
innermost part of the disc and equivalent to 10x speed
at the outermost part of the disc. This mode is selected
when the power is switched on with use of alkali batteries
or nicad batteries.

<Music CD playback>

[Normal playback: No display]

This mode is selected when the power is switched on.
Playback stops after the last track playback is completed.

[All tracks repeat: P ]

After the last track playback is completed, playback starts
again from the first track.
