1. SAFETY PRECAUTIONS

The following check should be performed for the continu-
ed 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 2292 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 120 V
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 OUT-
LINED 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 evi-
dent from visual inspection nor the protection afforded by
them necessarily can be obtained by using replacement com-
ponents 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
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 in-
structions are issued from time to time. For the latest informa-
tion, 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.

NOTES:
oParts without part number cannot be supplied.
