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

E
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 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.
Reading should
not be above
0.5 mA

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 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
information, always consult the current PIONEER
Service Manual. A subscription to, or additional copies
of, PIONEER Service Manual may be obtained at a
nominal charge from PIONEER.
