3、 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 preformed repairs can adversely affect the safety and reliability of the p

4、roduct and may void the warranty. If you are not a 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 Welfa

5、re 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, w

6、hen 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.

(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

8、Measure leakage current to a know 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.).

9、 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 no exceed 0.5mA. ANY MEASUREMENT NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RERTURNING THE APPLIANC

10、E TO THE CUSTOMER. 2.PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristic. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for vo

11、ltage, 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 D on the schematics and on the parts list in this Service Manual. The use of a substitute replacem

12、ent component which dose not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create sock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For th

13、e latest information, always consult the current PIONEER Service Manual.

Turn this knob clockwise to raise the level. Starting with “MIN“, turn this knob and raise the volume slowly. If the unit is turned on with the v

41、olume set too high, it could cause hearing and/or speaker damage. Do not turn the volume up excessively high. The low frequency sound is apt to be raised too high since it is less disturbing and harder to detect than high frequencies. Caution must be taken here since the amplifier and speaker of the

If the output of th

43、e amplifier (receiver) connected to this unit is high or if the output has a low range boosted by the Bass control, Bass boost, or other means, there may be some sound distortion even if the level of the unit is low- ered. In this case, lower the output level (Volume, Bass control, Bass boost) on th

This manufacturer and the Electronic Industries Associations Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud an

48、d clear without annoying blaring or distortion-and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. To establish a safe level: Start your volume control at a low setting. Slowly increase the sound until you can hear it comfortably and clearly, and without distortion. Once you have e
