Qualified technicians have the necessary te

4、st 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 product and may void the warranty. If you are not a qualified to perform the repair o

5、f 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 re

6、productive 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

7、ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation.

LEAKAGE CURRENT CHECK Measure leakage current to a know earth ground (water pipe, conduit, etc.) by connec

9、ting 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

10、 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 APPLIANCE TO THE CUSTOMER. 2.PRODUCT SAFETY NOTICE Many electrical and mechanical parts in t

11、he 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 voltage, wattage, etc. Replacement parts which have these special safety characteristi

12、cs 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 replacement component which dose not have the same safety characteristics as the PIONEER rec

13、ommended 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 the latest information, always consult the current PIONEER Service Manual. A subscript

Starting with “MIN“, turn this knob and raise the volume slowly. If the unit is turned on with the volume set too high, it could cause hearing and/or speaker damag

41、e. 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 HTP702-SW, HTP202/302-SW will be clipped when the output of th

42、e amplifier or receiver is increased with the subwoofer level set to “MAX“. 3 Subwoofer input terminal (LINE LEVEL INPUT) Connect SUBWOOFER OUTPUT terminal of the receiver to this terminal with the accessory RCA cord. 4 Subwoofer output terminal (LINE LEVEL OUTPUT) Used for connecting an additional

43、subwoofer to the system. Connect this terminal to the SUBWOOFER INPUT terminal of another subwoofer. If the output of the receiver connected to this unit is high or if the output has a low range boosted by the Bass con- trol, Bass boost, or other means, there may be some sound distortion even if the

44、 level of the unit is lowered. In this case, lower the output level (Volume, Bass control, Bass boost) on the receiver side. 6.
