(FOR USA MODEL ONLY)
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.
Reading should
Uaakage not be above
0.5mA
Test all
exposed metal
surfaces
S32
© Also test with
plug reversed
(Using AC adapter
plug as required)
Earth
ground
AC Leakage Test
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO-
TENTIAL SHOCK HAZARD AND MUST BE COR-
RECTED BEFORE RETURNING THE APPLIANCE TO
THE CUSTOMER.
2.PRODUCT SAFETY NOTICE
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 witha 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

Manual.
