This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a grounding plug.
It must be plugged into a wall receptacle that is properly installed and grounded in accordance with the National
Electrical Code and local codes and ordinances. In the event of an electrical short circuit, grounding reduces risk of
electric shock by providing an escape wire for the electric current.
WARNING – Improper use of the grounding plug can result in a risk of electric shock.
Electrical Requirements
The electrical requirements are a 120 volt 60 Hz, AC only, 15 amp. or more
protected electrical supply. It is recommended that a separate circuit serving
only this appliance be provided.
The oven is equipped with a 3-prong grounding plug. It must be plugged into a
wall receptacle that is properly installed and grounded. Should you only have a
2-prong outlet, have a qualified electrician install a correct wall receptacle.
A 3-prong adapter may be purchased and used temporarily if local codes allow.
Follow package directions.
A short power-supply cord is provided to reduce risk of becoming entangled in
or tripping over a longer cord.
Extension Cord
If it is necessary to use an extension cord, use only a 3-wire extension cord that
has a 3-blade grounding plug and a 3-slot receptacle that will accept the plug on
the microwave oven. The marked rating of the extension cord should be AC 115-
120 volt, 15 amp. or more.
Be careful not to drape the cord over the countertop or table where it can be
pulled on by children or tripped over accidentally.
Notes:
1. If you have any questions about the grounding or electrical instructions,
consult a qualified electrician or service person.
2. Neither Sharp nor the dealer can accept any liability for damage to the oven
or personal injury resulting from failure to observe the correct electrical
connection procedures.
Radio or TV Interference
Should there be any interference caused by the microwave oven to your radio or TV, check that the microwave oven
is on a different electrical circuit, relocate the radio or TV as far away from the oven as feasible or check position and
signal of receiving antenna.
UNPACKING AND INSTALLATION INSTRUCTIONS
GROUNDING INSTRUCTIONS
Unpacking and Examining Your Oven
Remove:
1. all packing materials from inside the oven cavity;
however, DO NOT REMOVE THE WAVEGUIDE
COVER, which is located on the right cavity wall.
Read enclosures and SAVE
the Operation Manual.
2. the feature sticker, if there
is one, from the outside of the
door.
Check the oven for any dam-
age, such as misaligned or
bent door, damaged door
seals and sealing surfaces,
broken or loose door hinges
and latches and dents inside the cavity or on the door.
If there is any damage, do not operate the oven and
contact your dealer or SHARP AUTHORIZED
SERVICER.
Choosing a Location for Your Oven
You will use the oven frequently so plan its location for
ease of use. It's wise, if possible, to have counter space
on at least one side of the oven. Allow at least 2 inches
on the sides, top and at the rear of the oven for air
circulation. Do not place or install the oven in any area
where heat and steam are generated; for example,
next to or above a conventional gas or electric range
or above a conventional wall oven. Heat and steam
may damage the electronics or the mechanical parts of
the oven.

Your oven can be built into a cabinet or wall—not
near or above a heat source—using Sharp’s Built-In Kit

plies Center. Have your credit card number available
