Installation and GROUNDING INSTRUCTIONS
Placement of the Oven
Locate the oven on a smooth, flat and stable surface.
There should be no gap between the table surface and
the bottom of the oven. Do not place the oven in a hot
or damp area, ie. near a stove, sink or directly above
heat lamps on a serving line. Free airflow around the
oven is important. There is a possibility of a small
amount of interference with weak broadcast signals if
the microwave oven is too close to a radio or TV.
Grounding Instructions
This oven must be grounded electrically. In the event of
an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the
electric current. The appliance is equipped with a cord
having a grounding wire with a grounding plug. The
plug must be plugged into an outlet that is properly
installed and grounded.
WARNING — improper use of the grounding plug can
result in a risk of electric shock.
Consult a qualified electrician or service person if the
grounding instructions are not completely understood,
or if doubt exists as to whether the appliance is
properly connected.
If it is necessary to use an extension cord, use only a
three wire extension cord that has a three blade
grounding plug, and a three slot receptacle that will
accept the plug on the appliance. The marked rating of
the extension cord should be equal to or greater than
the electical rating of the oven.
Removal of Protective Film
A blue protective film is used to prevent scratching of
the outer case during transportation. Peel the film from
the exterior of the oven before installation or use.
Wiring Requirements
No other appliance should share the circuit with the
microwave oven. If it does, the branch circuit fuse may
overload and either cause the oven to heat slower than
expected or blow the fuse.
A. For Model NE-1257/NE-1258
The oven must be on a SEPARATE, 20 amp,
60 Hz-120 V GROUNDED CIRCUIT.

B. For Models NE-1757/NE-2157
1. This oven must be on a separate, 60 Hz
GROUNDED CIRCUIT - minimum 15 amps for
NE-1757; minimum 20 amps for NE-2157.
2. The microwave ovens are built to operate on 2
different voltages (230-240 V or 208 V). Be sure
that the voltage selector connector (on the back of
the oven) is set for your power supply (see
page 5). Using a higher voltage setting is
dangerous and may result in overheating of the
electrical components thus shortening their life
expectancy or possibly causing a fire or other
accident. Using a lower voltage will lower the
power output of the oven, resulting in slower
heating of the food. Panasonic is NOT responsible
for damage resulting from the use of the oven with
other than the specified voltage.

Caution
Do not attempt to tamper with or make any 1.
adjustments or repairs to the door, control panel
housing, safety interlock switches or any other part
of the oven. Do NOT remove the outer panel of the
oven. Repairs should only be done by a qualified
service person.
Do NOT operate the oven empty. The microwave 2.
energy will reflect continuously throughout the oven
if no food or water is present to absorb energy.
If a fire occurs in the oven, press the Stop/Reset 3.
Pad and LEAVE THE DOOR CLOSED. Disconnect
the power cord, or shut off the power at the fuse or
circuit breaker panel.
Do NOT attempt to dry clothes, newspapers or 4.
other materials in the oven, as they may catch on
fire.
Do NOT use recycled paper products, as they may 5.
contain impurities which may cause sparks and/or
fires.
Do NOT use newspapers or paper bags for cooking. 6.
Do NOT hit or strike the control panel. Damage to 7.
controls may occur.
POT HOLDERS may be needed when removing 8.
food from the oven. Heat is transferred from the hot
food to the container.
Do NOT store flammable materials next to, on top 9.
of, or in the oven. It could be a fire hazard.
Do NOT operate the oven without the spatter 10.
shields (located in the top of inner cavity) in place.
