(FOR CANADIAN MODEL ONLY)
(fast operating fuse) and/or
(slow operating fuse) on PCB indicate that replacement
parts must be of identical designation.
(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.
(FOR USA MODEL ONLY)
The following check should be performed for the
continued protection of the customer and service
LEAKAGE CURRENT CHECK
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.). 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
APPLIANCE TO THE CUSTOMER.
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
voltage, wattage, etc. Replacement parts which have
these special safety characteristics are identified in this
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 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 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
