SAFETY INFORMATION 1. SAFETY PRECAUTIONS The following check should be performed for the continued protection of

5、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 specia

6、l 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

7、 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 o

8、ne, 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- dition

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 e

10、xposed 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

11、 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 MODLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type

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. This service manual is intended for qualif

13、ied 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 th
