Health & Safety Code Section 25249.6 – Proposition 65
NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts
must be of identical designation.

Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les
pièces de remplacement doivent avoir la même désignation.
(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 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
Earth ground
Device
under
test
Also test with plug
reversed
(Using AC adapter
plug as required)
Leakage
current
tester
Test all exposed
metal surfaces
AC Leakage Test
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.
