GENERAL PRECAUTIONS IN USE

Microwave Oven
A. Never operate the unit when it is empty. Operating
the oven with no load may shorten the life of the
magnetron. Whenever cooking dry foods (dried fish,
bread, etc.) or a small amount of food, be sure to
put a glass of water into the cooking compartment.
The turntable tray may become hot after operating,
be careful when touching it.
B. Aluminum foil should be avoided because it will
disrupt cooking and may cause arcing. However,
small pieces may be used to cover some parts of
food to slow the cooking. Any aluminum foil used
should never be closer than 2.5 cm to any side wall
of the oven.
Toaster
A. Never operate the toaster when it is empty.
Operating the toaster with no load may overheat this
appliance.
B. Oversized food, metal foil packages or utensils must
not be inserted in this toaster, as they may create a
fire or electrical hazards.
