reduces risk of electric shock by providing an escape wire for the electric current. It is
recommended that a separate circuit serving only the oven be provided. Using a high

6
voltage is dangerous and may result in a fire or other accident causing oven damage.
WARNING!--Improper use of the grounding plug can result in a risk of electric shock.
Note:
1. If you have any questions about the grounding or electrical instructions, consult a
qualified electrician or service person.
2. Neither the manufacturer nor the dealer can accept any liability for damage to the
oven or personal injury resulting from failure to observe the electrical connection
procedures.

3. Relocate the microwave oven with respect to the receiver.
4. Move the microwave oven away from the receiver.
5. Plug the microwave oven into a different outlet so that microwave oven and receiver
are on different branch circuits.
BEFORE CALLING FOR SERVICE
Before asking for service, please check each item below:
Check to ensure the oven is plugged in securely. If not, remove the plug from the
outlet, wait 10 seconds, and plug it in again securely.
Check for a blown circuit fuse or a tripped main circuit breaker. If these seem to be
operating properly, test the outlet with another appliance.
Check to ensure the control panel is programmed correctly and the timer is set.
Check to ensure the door is securely closed, engaging the door lock system. If the
door is not properly closed, the microwave energy will not flow inside.
IF NONE OF THE ABOVE RECTIFIES THE SITUATION, THEN CONTACT A
QUALIFIED TECHNICIAN. DO NOT TRY TO ADJUST OR REPAIR THE OVEN
YOURSELF.

COOKING TECHNIQUES
1. Arrange food carefully. Place thickest areas towards outside of dish.
2. Watch cooking time. Cook for the shortest amount of time indicated and add more
as needed. Food severely overcooked can smoke or ignite.
3. Cover foods while cooking. Covers prevent spattering and help foods to cook
evenly.
4. Turn foods over once during microwave cooking to speed cooking of such foods as
chicken and hamburgers. Large items like roasts must be turned over at least once.
5. Rearrange foods such as meatballs halfway through cooking both from top to
bottom and from the center of the dish to the outside.
COOKING UTENSILS GUIDE
1. Microwave cannot penetrate metal. Only use utensils that are suitable for use in
microwave ovens. Metallic containers for food and beverages are not allowed during
microwave cooking. This requirement is not applicable if the manufacturer specifies
size and shape of metallic containers suitable for microwave cooking.
2. Microwave cannot penetrate metal, so metal utensils or dishes with metallic trim
should not be used.
3. Do not use recycled paper products when microwave cooking, as they may contain
small metal fragments which may cause sparks and/or fires.
4. Round /oval dishes rather than square/oblong ones are recommended, as food in
corners tends to overcook.
5. Narrow strips of aluminum foil may be used to prevent overcooking of exposed
areas. But be careful don’t use too much and keep a distance of 1 inch (2.54cm)
between foil and cavity.
The list below is a general guide to help you select the correct utensils.

oven walls, wipe with a damp cloth. Mild detergents may be used if the oven gets
very dirty. Avoid using spray or other harsh cleaners. They may stain, streak or dull
the door surface.
3. The outside of the oven should be cleaned with a damp cloth. To prevent damage to
the operating parts inside the oven, water should not be allowed to seep into the
ventilation openings.
4. Wipe the door and window on both sides, the door seals and adjacent parts
frequently with a damp cloth to remove any spills or spatters. Do not use abrasive
cleaner.

15
5. A steam cleaner is not be used.
6. Do not allow the control panel to become wet. Clean with a soft, damp cloth. When
cleaning the control panel, leave oven door open to prevent oven from accidentally
turning on.
7. If steam accumulates inside or around the outside of the oven door, wipe with a soft
cloth. This may occur when the microwave oven is operated under high humidity
condition. And it is normal.
8. It is occasionally necessary to remove the glass tray for cleaning. Wash the tray in
warm sudsy water or in a dishwasher.
9. The roller ring and oven floor should be cleaned regularly to avoid excessive noise.
Simply wipe the bottom surface of the oven with mild detergent. The roller ring may
be washed in mild, soapy water or in a dishwasher. When removing the roller ring,
be sure to replace it in the proper position.
10. Remove odors from your oven by combining a cup of water with the juice and skin of
one lemon in a microwaveable bowl. Microwave for 5 minutes. Wipe thoroughly and
dry with a soft cloth.
11. If the light bulb burns out, please contact customer service to have it replaced.
12. The oven should be cleaned regularly and any food deposits should be removed.
Failure to maintain the oven in a clean condition could lead to deterioration of
surface that could adversely affect the life of the unit and could possibly result in a
hazardous situation.
13. Please do not dispose of this appliance into the domestic rubbish bin; it should be
disposed to the particular disposal center provided by the municipalities.
14. When the microwave oven with grill function is first used, it may produce slight
smoke and smell. This is a normal phenomenon, because the oven is made of a
steel plate coated with lubricating oil, and the new oven will produce fumes and odor
generated by burning the lubricating oil. This phenomenon will disappear after a
period of using.
