Leakage Current Check: To ensure safety,
measure leakage current to a known earth ground using a leakage
current tester. The current should not exceed 0.5 mA.

2. Product Safety Notice:

It is essential to use replacement parts with special safety
characteristics as identified in the service manual. Substituting
with components lacking these safety features may pose hazards.

FAQ:

Q: Where can I obtain additional copies of the Pioneer Service

Manual?

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
B This product may contain a chemical known to the State of California to cause cancer, or birth defects or other reproductive harm. Health & Safety Code Section 25249.6 – Proposition 65

1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
D 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.

E
Device under test

Leakage current tester

Reading should not be above 0.5 mA

Test all exposed metal surfaces

Also test with

plug reversed

(Using AC adapter

F

plug as required)

Earth ground

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE
LIMITS OUTLINED ABOVE ARE INDICATIVE
OF A POTENTIAL SHOCK HAZARD AND
MUST BE CORRECTED BEFORE RETURN-
ING 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 schematics and 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.

1. CONTRAST OF MISCELLANEOUS PARTS

NOTES: Parts marked by “NSP” are generally unavailable because they are not in our Master Spare Parts List.

The mark found on some component parts indicates the importance of the safety factor of the part.

A

Therefore, when replacing, be sure to use parts of identical designation.

Screws adjacent to mark on product are used for disassembly.

For the applying amount of lubricants or glue, follow the instructions in this manual.

(In the case of no amount instructions, apply as you think it appropriate.)

Nos. indicate the pages and Nos. in the service manual for the base model.

When ordering resistors, first convert resistance values into code form as shown in the following examples.

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,

and K=10%).
