IMPORTANT SAFETY INSTRUCTIONS.
READ ALL INSTRUCTIONS BEFORE USING.
WARNING!
GROUNDING INSTRUCTIONS
Improper use of the grounding plug can result in a risk of electric shock.
This appliance must be grounded. In the event
of an electrical short circuit, grounding reduces
the risk of electric shock by providing an
escape wire for the electric current.
This appliance is equipped with a power cord
having a grounding wire with a grounding
plug. The plug must be plugged into an outlet
that is properly installed and grounded.
Consult a qualified electrician or service
technician if the grounding instructions are not
completely understood, or if doubt exists as to
whether the appliance is properly grounded.
If the outlet is a standard 2-prong wall outlet,
it is your personal responsibility and obligation
to have it replaced with a properly grounded
3-prong wall outlet.
EXTENSION CORDS
A short power supply cord is provided to
reduce the risks resulting from becoming
entangled in or tripping over a longer cord.
Extension cords may be used if you are careful
in using them.
If an extension cord is used:
The marked electrical rating of the
extension cord should be at least as great
as the electrical rating of the appliance;
The extension cord must be a grounding-
type 3-wire cord and it must be plugged
into a 3-slot outlet;
6
Do not under any circumstances cut or remove
the third (ground) prong from the power cord.
We do not recommend using an extension cord
with this appliance. If the power cord is too
short, have a qualified electrician or service
technician install an outlet near the appliance.
(See Extension Cords section.)
For best operation, plug this appliance into
its own electrical outlet to prevent flickering
of lights, blowing of fuse or tripping of
circuit breaker.
The extension cord should be arranged so
that it will not drape over the countertop
or tabletop where it can be pulled on by
children or tripped over unintentionally.
If you use an extension cord, the interior light
may flicker and the blower sound may vary
when the microwave oven is on. Cooking times
may be longer, too.
