PRECAUTIONS

TO

AVOID POSSIBLE EXPOSURE

TO

EXCESSIVE MICROWAVE ENERGY

A.

DO NOT attempt to operate this oven with the door open since open door operation can result

in harmful exposure to microwave energy. It is important not to defeat or tamper with the safety interlocks.

B.

DO NOT place any object between the oven front face and the door or allow soil or cleaner

residue to accumulate on sealing surfaces.

C.

DO NOT operate the oven if it is damaged.

It

is particularly important that the oven door close

properly and that there is no damage to the:

1.

door (bent)

2.

hinges and latches (broken or loosened)

3.

door seals and sealing surfaces.

D. The oven should not be adjusted or repaired by anyone except properly qualified service

personnel.

4

To avoid risk of personal injury or property damage, observe the following safety instructions:

General Use:

1.

Do not use regular cooking thermometers in oven. Most cooking thermometers contain mercury and may cause an electrical arc, malfunction, or damage to oven.

2.

Never use paper, plastic, or other combustible materials that are not intended for cooking.

3.

When cooking with paper, plastic, or other combustible materials, follow manufacturer’s recommendations on product use.

4.

Do not use paper towels which contain nylon or other synthetic fibers. Heated synthetics could melt and cause paper to ignite.

5.

To avoid surface deterioration, keep the oven in a clean condition. Infrequent cleaning could adversely affect the life of the appliance and possible result in a hazardous situation.

6.

Clean oven regularly and remove any food deposits.

Heating Foods and Liquids:

7.

Liquids such as water, coffee, or tea are able to be overheated beyond the boiling point without appearing to be boiling due to surface tension of the liquid. Visible bubbling or boiling when the container is removed from the microwave oven is not always present. THIS COULD RESULT IN VERY HOT LIQUIDS SUDDENLY BOILING OVER WHEN A SPOON OR OTHER UTENSIL IS INSERTED INTO THE LIQUID. To reduce the risk of injury to persons:

• Do not overheat the liquid.

• Stir the liquid both before and halfway through heating it.

• Do not use straight-sided containers with narrow necks.

• After heating, allow the container to stand in the microwave for a short time before removing it.

b.

Use extreme care when inserting a spoon or other utensil into the container.

8.

Do not deep fat fry in oven. Fat could overheat and be hazardous to handle.

9.

Do not cook or reheat eggs in shell or with an unbroken yolk using microwave energy. Pressure may build up and erupt. Pierce yolk with fork or knife before cooking.

10.

Pierce skin of potatoes, tomatoes, and similar foods before cooking with microwave energy. When skin is pierced, steam escapes evenly.

11.

Do not heat sealed containers or plastic bags in oven. Food or liquid could expand quickly and cause container or bag to break. Pierce or open container or bag before heating

12.

Do not heat baby bottles in oven.

13.

Baby food jars shall be open when heated and contents stirred or shaken before consumption, in order to avoid burns.

14.

Never use oven to heat alcohol or food containing alcohol as it can more easily catch fire if overheated.

Additional Microwave Oven Safety Instructions:

15.

Do not operate equipment without load or food in oven cavity.

16.

Use only popcorn in packages designed and labeled for microwave use. Popping time varies depending on oven wattage. Do not continue to heat after popping has stopped. Popcorn will scorch or burn. Do not leave oven unattended.

17.

Do not use metal utensils in oven.

18.

An authorized servicer MUST inspect equipment annually. Record all inspections and repairs for future use.
