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 charac-
teristics 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.
