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.
REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
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.
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 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
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.
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.
(FOR USA MODEL ONLY)
