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
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
