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 tum the AC power switch on. Any
current measured must not exceed 0.5mA.
hal Reading should
Leakage
not be above
current | 0-S5mA
Test all
exposed metal
surfaces
Also test with
plug reversed
(Using AC adapter
plug as required)
2- 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
indentified 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, or ad- |
ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.
"CAUTION-Laser radiation when open and interlock defeated. DO NOT STARE INTO BEAM."
