ARCING
If you see arcing, press the CLEAR/OFF pad and correct the problem.
Arcing is the microwave term for sparks in the
oven. Arcing is caused by:
....Metal or foil toudfing tile side of the oven.
....Foil not molded to food (upturned edges
act like antennas).

geM-rimmed dishes, in the microwave.
.... R ecycled paper towels containing small
metal pieces being used in the microwave.
SUPER HEATED WATER
Microwaved water and other liquids do not always bubble when they reach the boiling point.
They can actually get super heated and not bubble at all.
Super heated liquid will bubble up out of the
cup when it is moved or when something like
a spoon or tea bag is put into it.
To prevent this fiom happening and causing
i_ju U, do not heat aW liquid for more than 2
ufinutes per cup.
Mter heating, let tile cup stand in the
microwave for 30 seconds before moving it or
putting awthing into it.
Spontaneous boiling
Under certain special circumstances, liquids
may start to boil during or shortly after removal
from the microwave oven.
To prevent burns from splashing liquid, we
recommend the folk_wing before removing
the container fiom the oven:
Mlow the container to stand in the oven ff)r
30 to 40 seconds after the oven has shut or1:
Do not boil liquids in narrow-necked
containers such as soft drink bottles, wine
flasks and especially narrow-necked cottce
cups. Even it the container is opened,
excessive steam can build up and cause it
to
burst or overflow.
