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 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 RETURN- ING 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. (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 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. Device under test Leakage current tester Earth ground Reading should not be above 0.5 mA Also test with plug reversed (Using AC adapter plug as required) Test all exposed metal surfaces 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 SE-DIR800C 3 5 6 7 8 5 6 7 8 C D F A B E CONTENTS SAFETY INFORMATION......................................................................................................................................2 1.

PCB PARTS LIST LIST OF ASSEMBLIES 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%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5 6 1 4 7 3 R 5 0 1 R 0 5 6 2 1 NOTES: 560 Ω 47k Ω 0.5 Ω 1 Ω RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 10 1 47 x 10 3 R50 1R0 561 473 5.62k Ω RN1/4PC F 562 x 10 1 5621 Mark Symbol and Description SE-DIR800C /KUCXCN SE-DHT800C /NYXCN NSP 1..DIGITAL CORDLESS HEADPHONE WPH1021 WPH1021 NSP 1..Composite PCB ASSY WNX1019 WNX1019 2..MAIN PCB ASSY WWX1065 WWX1065 2..Power PCB ASSY WWX1066 WWX1066 NSP 2..L.PHOTO PCB ASSY WWX1068 WWX1068 NSP 2..R.PHOTO PCB ASSY WWX1069 WWX1069 NSP 1..TRANSMITTER WPX1010 WPX1010 NSP 1..Gathering PCB ASSY WNX1020 WNX1020 2..
