(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 not

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 A 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 ServiceManual, 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,
