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 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 PO- TENTIAL SHOCK HAZARD AND MUST BE COR- RECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appli- ance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be ob- tained 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 ad- ditional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. 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. (FOR USA MODEL ONLY) Also test with plug reversed (Using AC adapter plug as required) Device under test Test all exposed metal surfaces Earth ground Leakage current tester Reading should not be above 0.5 mA AC Leakage Test 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. 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. 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 F-208 2.1 PACKING 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 ......................................................................

PANEL FACILITIES AND SPECIFICATIONS 8.1 PANEL FACILITIES 1� STANDBY/ON switch This is the switch for electric power. ON ..................When set to ON position, power is supplied and the unit becomes operational. STANDBY .......When set to STANDBY position, the main power flow is cut and the unit is no longer fully operational. A minute flow of power feeds the unit to maintain operation readiness. NOTES: ¶ The memory will be backed up so long as the power cord is unplugged. ¶ If the power cord is unplugged, the memory will be retained for several days. ¶ When not using the unit for a long period, disconnect the power cord. 2� MEMORY SCAN button When this button is pressed, preset stations within a class (A, B or C) are received in order. 6� MEMORY button Use to preset stations. This is also used for FM or AM broadcast manual station name character selection. 3� CHARACTER button You can use it to input station names manually. (see page 12) 7� CLASS button Use to switch between preset memory classes A to C. In each class, 10 stations can be memorized using the STATION CALL buttons, enabling a total of 30 stations to be memorized. 8 DIRECT button When this button is pressed, the STATION CALL buttons function as ten-key number buttons for direct input of the desired reception frequency. Press again to cancel this mode. 9 TUNING MODE button Each time you press this button, the TUNING knob's function changes as follows. 0 TUNING knob Use for tuning. To raise the frequency, turn in a clockwise direction; to lower the frequency, turn counterclockwise. In the Station Name input mode, the TUNING knob is used to select characters. When presetting a station or selecting a preset station, you can also turn this knob to select a desired station number. 5� Operating display Manual tuning mode Auto tuning mode Preset station tuning mode 4� DISPLAY MODE button When in the Preset Station Selection mode, pressing this button changes display indications. If no station names are memorized, this button has no function. When no station name is memorized,the DISPLAY MODE button becomes invalid.

This button does not affect AM reception. AUTO: “AUTO”is not displayed. Normally leave in this mode for reception. When a stereo FM broadcast is received, it will be automatically reproduced in stereo sound and the STEREO indicator lights up. ~� BAND button The button is used to select either FM or AM reception. !� STATION CALL buttons Use these buttons to preset stations and to receive the already preset stations. These are also used when performing direct access tuning. MONO: MONO indicator lights up. To receive stereo broadcasts in monaural. If there is too much noise during stereo reception of a weak signal, you can reduce the level of noise by switching to MONO. NOTES: ¶ This button’s status is preset for each station in station memory. ¶ When the signal level is too weak for reception, sound output is automatically muted. If sound is muted when the selected mode is AUTO, switching to MONO lets you hear the broadcast. AUTO MONO -� RF ATT button Set this button to on when receiving strong FM signals (nearby stations) to reduce sound distortion (RF ATT indicator lights). Normally, this button should be set to off. This button does not affect AM reception. NOTE: This button’s status is preset for each station in station memory.
