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 60Hz outlet and turn the AC power
switch on. Any current measured must not exceed 0.5mA.
ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED
ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD
AND MUST BE CORRECTED BEFORE RETURNING 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
Product Safety is continuously under review and new
