SAFETY INFORMATION
A
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
This product contains and certain electrical parts contain chemicals which are known to the state of California to cause cancer,
B
birth defects or other reproductive harm.
Health & Safety Code Section 25249.6 – Proposition 65
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
C
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
D
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.

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.

Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by
following the safety instructions described in this manual.
1 Use specified parts for repair.
Use genuine parts. Be sure to use important parts for safety.
2 Do not perform modifications without proper instructions.
Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as
radio/TV interference and foreign noise.
3 Make sure the soldering of repaired locations is properly performed.
When you solder while repairing, please be sure that there are no cold solder and other debris.
Soldering should be finished with the proper quantity. (Refer to the example)
4 Make sure the screws are tightly fastened.
Please be sure that all screws are fastened, and that there are no loose screws.
5 Make sure each connectors are correctly inserted.
Please be sure that all connectors are inserted, and that there are no imperfect insertion.
6 Make sure the wiring cables are set to their original state.
Please replace the wiring and cables to the original state after repairs.
In addition, be sure that there are no pinched wires, etc.
7 Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
0 Safe environment should be secured during servicing.

2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
