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
ANY
MEASUREMENTS

INDICATIVE
OF
A

Many electrical and mechanical parts in the appli-
ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob-
tained by using replacement components rated for vol-
tage, 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 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,

ditional copies of, PIONEER
Service Manual may be
