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

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

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.

5. PCB PARTS LIST

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. Therefore, when replacing, be sure to use parts of identical designation. 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%). 561... RD1/4PU 1 J 560 473... RD1/4PU 3 J 47k 0.5 R50... RN2H R K 1 1R0... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5621.. RN1/4PC F 5.62k

Press and hold the button for more than 3 seconds to switch SB mode ON. (Volume indicator goes out) Press and hold the button for more than 3 seconds again to switch SB mode OFF. (Volume indicator lights) [DIRECT] Use this button when you do not wish to pass the output from input terminal equipment through the various frequency adjusting circuits (BASS, TREBLE, BALANCE, LOUDNESS). On : The indicator lights. The signals input through the input terminals are reproduced without passing through the various frequency adjusting circuits. This results in flat, pure sound which is a more faithful reproduction of the input source. Off : The indicator goes out. The signal passes through the various frequency adjusting circuits. [SB MODE] The SB mode is a special mode in which the amplifier does not accept remote control except power ON/OFF (But all of the facilities can be controled by manual as same as SB mode OFF.). Fix the VOLUME control near the center position.In this mode, the set can be used as a power amplifier which amplifies the LINE/SURROUND BACK input (the function name is LINE/SB) with a input sensitivity of 1V. For example, when the set is combined with one of Pioneer's Surround Back compatible receiver, the set can be used sa the Surround Back amplifier. (For details, please refer to the instruction manual of the receiver.)

@ SPEAKERS A (ON/OFF) button/indicator
