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

2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appliance
have special safety related character istics. 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 par ts which have these
special safety character istics are identified in this
Service Manual.
Electr ical 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
infor mation, always consult the current PIONEER
Ser vice Manual. A subscription to, or
additional copies
of, PIONEER Ser vice Manual may be obtained at a

1. SAFETY PRECAUTIONS
The following check should be perfor med for the
continued protection of the customer and ser vice
technician.
LEAKAGE CURRENT CHECK
Measure leakage current to a known ear th ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
equivalent between the ear th ground and all exposed
metal par ts of the appliance (input/output ter minals,
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.
