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 THELIMITS OUTLINED ABOVE ARE INDICATIVEOF A POTENTIAL SHOCK HAZARD ANDMUST BE CORRECTED BEFORE RETURN-ING THE APPLIANCE TO THE CUSTOMER.
2. PRODUCT SAFETY NOTICEMany electrical and mechanical parts in the appliance
have special safety related character istics. These areoften not evident f rom visual inspect ion nor theprotection afforded by them necessarily can be obtainedby using replacement components rated for voltage,wattage, etc. Replacement par ts which have thesespecial safety character ist ics are identif ied in thisService Manual.
Electr ical components having such features areidentified by marking with a on the schematics andon the parts list in this Service Manual.The use of a substitute replacement component whichdoes not have the same safety characteristics as thePIONEER recommended replacement one, shown in theparts list in this Service Manual, may create shock, fire,or other hazards.

(FOR USA MODEL ONLY)1. SAFETY PRECAUTIONS
The following check should be performed for thecont inued protect ion of the customer and servicetechnician.
LEAKAGE CURRENT CHECKMeasure leakage current to a known ear th ground
(water pipe, conduit, etc.) by connecting a leakagecurrent tes ter such as S impson Model 229-2 orequivalent between the earth ground and all exposedmetal par ts of the appliance (input/output terminals,screwheads, metal overlays, control shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on. Anycurrent measured must not exceed 0.5 mA.
Deviceundertest

5. PCB PARTS LIST
XWK3101 and XWK3096 are constructed the same except for the following :
XWZ3659 and XWZ3658 are constructed the same except for the following :
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).

7.4 CLEANING
1. DC-abnormality detectionIn the case of simultaneous detection with the overload protection circuit, DC-abnormality detection is performed preferentially to overload detection.
In the case of simultaneous detection with the overload protection circuit, Board detection is performed preferentially to DC-abnormality detection and Overload detection.
*A.MUTE : Audio mute command
↓
The abnormality continues for 3 seconds.
↓ Continues. ↓ Recovery
The power is shut off. The program restarts.
↓The power key is disabled and Standby LED blinks.
But be switched on with the following methods.1 TESTMODE ON (A55F+A55F)2 When power off, push FRONT ENTER key + ADVANCED SURROUND key continuously 2sec.(2: When a DC abnormality is detected and the power is shut off.)
2. Overload detection
↓
The abnormality continues for 3 seconds.
↓ Continues. ↓ Recovery
The power is shut off.The power is shut off even if the
unit recovers.
When a DC abnormality is detected, A.MUTE* is turned on, speaker relay is turned off, then "AMP_ERR" flashes on the display.
When an overload is detected, A.MUTE* is turned on, speaker relay is turned off, then
"OVERLOAD" flashes on the display.
3. Board detection
↓
The abnormality continues for 3 seconds.
↓ Continues. ↓ Recovery
The power is shut off.The power is shut off even if the
unit recovers.
When an boad error is detected, A.MUTE* is turned on, speaker relay is turned off, then
"BOAD ERR" flashes on the display.
