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. 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. 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 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA. (FOR USA MODEL ONLY) Leakage current tester Reading should not be above 0.5mA Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) Earth ground AC Leakage Test www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 3 A-307R, A-207R 2.1 PACKING Mark No. Description Part No. 2.

PCB PARTS LIST 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. 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%). 560 Ω → 56 × 10 1 → 561 ........................................................ RD1/4PU 5 6 1 J 47k Ω → 47 × 10 3 → 473 ........................................................ RD1/4PU 4 7 3 J 0.5 Ω → R50 ..................................................................................... RN2H R 5 0 K 1 Ω → 1R0 ..................................................................................... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω → 562 × 10 1 → 5621 ......................................................

Turning the knob clockwise causes the lit indicator to right. Turning counter- clockwise 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 : Set to this position when listening to the program from a component connected to the LINE terminals. TAPE 1/MD : For playback with a cassette deck or MD recorder connected to TAPE 1/MD terminals. 5 TAPE 2 MONITOR button/indicator Use when there is an adaptor component (graphic equalizer, etc.) or cassette deck connected to the TAPE 2 MONITOR terminals. On : Indicator lights when using the adaptor component or listening to the cassette deck. Off : Indicator goes off when not in use. NOTES: ÷ When no connections are made to the TAPE 2 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 TAPE 2 MONITOR indicator is on and the INPUT SELECTOR knob is not set to TAPE 1/MD, the signals which are input through TAPE 2 MONITOR are then output at TAPE 1/MD REC OUT. 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.
