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 This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, 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 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.
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 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.

2 REMOTE CONTROL SENSOR window 3 VOLUME control
Use to adjust the volume level.
NOTES:
÷ When no connections are made to the TAPE2 MONITOR terminals, or when they are not in use, be sure to set this switch to the off position. (No sound will be heard if it is set to the on position.) ÷ When the TAPE2 MONITOR indicator is on and the INPUT SELECTOR knob is not set to TAPE1/CD-R/MD, the signals which are input through TAPE 2 MONITOR are then output at TAPE1/CD-R/MD REC OUT.
4 INPUT SELECTOR knob/indicators
Turn the knob clockwise or counterclockwise so that the indicator lights for your desired input source. Turning the knob clockwise causes the lit indicator to right. Turning counterclockwise causes it to left. CD : For compact disc playback with a CD player. TUNER : For AM or FM broadcast reception with a tuner. PHONO : For record playback with a turntable. LINE/SB : Set to this position when listening to the program from a component connected to the LINE/SURROUND BACK terminals. TAPE 1/ : For playback with a cassette deck, CD CD-R/MD recorder or MD recorder connected to TAPE1/ CD-R/MD terminals.
6 BALANCE control
Should normally be left in the center position. Adjust balance if the sound is louder from one of the speakers. If the right side is louder, turn toward the L (left) position and if the left side is louder, turn toward the R (right) position.
NOTE:
This control does not operate when the DIRECT button is in the on position.

7 DIRECT button/indicator
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 passing 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 off: The signal passes through the various frequency adjusting circuits.
- SPEAKERS B (ON/OFF) button/indicator
Use this button to listen to the speaker system connected to SPEAKERS B terminals. ON : The indicator lights. Sound is heard from the speaker system. OFF : The indicator goes off. No sound is heard from the speaker system. Set to this position when listening with headphones.

8 SB MODE button/indicator
The SB mode is a special mode in which the amplifier does not accept remote control (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 1 V. For example, when the set is combined with one of Pioneer's Surround Back compatible receiver, the set can be used as the Surround Back amplifier (For details, please refer to the instruction manual of the receiver.)
NOTE:
The speakers continue to output sound even when headphones are plugged into this jack. To mute the sound from the speakers, press the SPEAKERS button to OFF.
~ SPEAKERS A (ON/OFF) button/indicator
