2. WARNING: Check the oven for any damage, such as misaligned or bent door, damaged door seals and  
sealing surface, broken or loose door hinges and latches and dents inside the cavity or on the door. If  
there is any damage, do not operate the oven and contact qualified service personnel.  
3. This microwave oven must be placed on a flat, stable surface to hold its weight and the heaviest food  
likely to be cooked in the oven.  
4. Do not place the oven where heat, moisture, or high humidity are generated, or near combustible  
materials.  
5. For correct operation, the oven must have sufficient airflow. Allow 20cm of space above the oven, 10cm  
at back and 5cm at both sides. Do not cover or block any openings on the appliance. Do not remove  
feet.  
6. Do not operate the oven without glass tray, roller support, and shaft in their proper positions.  
7. Make sure that the power supply cord is undamaged and does not run under the oven or over any hot or  
sharp surface.  
8. The socket must be readily accessible so that it can be easily unplugged in an emergency.  
9. Do not use the oven outdoors.  
GROUNDING INSTRUCTIONS  
This appliance must be grounded. This oven is equipped with a cord having a grounding wire with a  
grounding plug. It must be plugged into a wall receptacle that is properly installed and grounded. In the event  
of an electrical short circuit, grounding 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  
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.  
The wires in this cable main are colored in accordance with the following code:  
Green and Yellow = EARTH  
Blue = NEUTRAL  
Brown = LIVE  
RADIO INTERFERENCE  
Operation of the microwave oven can cause interference to your radio, TV, or similar equipment.  
When there is interference, it may be reduced or eliminated by taking the following measures:  
1. Clean door and sealing surface of the oven.  
2. Relocate the receiving antenna of radio or television.  
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.

6. Place the cookware in the cavity along with a glass half full of water .Heat on 900 W (100%) for one  
minute,If the cookware feels hot,you should not use it.If it is just slightly warm,you can use it for reheating  
but not for cooking.If the dish is room temperature,it is suitable  
Paper napkins ,wax paper,paper towels,plates,cups,cartons,freezer wrap and cardboard are great  
convenience utensils.Always be sure containers are filled with food to absorb energy and thus avoid the  
possibility of over heating .  
Many plastic dishes,cups,freezer containers and plastic wraps may be used in the microwave  
oven.Follow manufacturer’s instructions when using plastics in the oven.Avoid using plastic utensils with  
foods that have high fat or sugar content since these foods reach high temperatures and could melt  
some plastics.  
Do not leave oven unattended,and look at it from time to time when heating or cooking food in  
plastic,paper or other combustible containers.If smoker is observed,keep door closed,switch the oven  
until smoke stops.  
Metal utensils and utensils with metallic trim should not be used in the microwave oven,unless  
specifically recommended for microwave use .  
Containers with restricted openings,such as bottles,should not be used for microwave cooking.  
Use caution when removing a lid or cover from a dish to avoid steam burns.  
7. WARNING: Liquid or other food must not be heated in sealed containers since they are liable to explode.  
8. Microwave heating of beverage can result in delayed eruptive boiling, therefore care has to be taken  
when handle the container.  
9. Do not fry food in the oven. Hot oil can damage oven parts and utensils and even result in skin burns.  
10. Eggs in their shell and whole hard-boiled eggs should not be heated in microwave ovens since they may  
explode even after microwave heating has ended.

12. The contents of feeding bottles and baby jars should be stirred or shaken and the temperature should be  
checked before serving in order to avoid burns.  
13. Cooking utensils may become hot because of heat transferred from the heated food. Potholders may be  
needed to handle the utensil.  
14. Utensils should be checked to ensure that they are suitable for use in microwave oven.  
15. WARNING: It is hazardous for anyone other than a trained person to carry out any service or repair  
operation which involves the removal of any cover which gives protection against exposure to microwave  
energy.

COOKING TIPS  
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 burn or ignite.  
3. Cover foods while cooking. Covers prevent spattering and help foods to cook evenly.  
4. Turn foods over once during 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.  
UTENSILS GUIDE  
1. The ideal material for a microwave utensil is transparent to microwave, it allows energy to pass through  
the container and heat the food.  
2. Microwave can not 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 recommend, 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.

CLEANING AND CARE  
1. Turn off the oven and remove the power plug from the wall socket before cleaning.  
2. Keep the inside of the oven clean. When food splatters or spilled liquids adhere to oven walls,  
wipe with a damp cloth. Mild detergent may be used if the oven gets very dirty. Avoid the use of  
spray and other harsh cleaners as they may stain, streak or dull the door surface.  
3. The outside surfaces 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.  
5. 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.  
6. 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.  
7. It is occasionally necessary to remove the glass tray for cleaning. Wash the tray in warm sudsy  
water or in a dishwasher.  
8. 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 sudsy  
water or dishwasher. When removing the roller ring from cavity floor for cleaning, be sure to  
replace in the proper position.  
9. Remove odors from your oven by combining a cup of water with the juice and skin of one lemon  
in a deep microwaveable bowl, microwave for 5 minutes. Wipe thoroughly and dry with a soft  
cloth.  
10. When it becomes necessary to replace the oven light, please consult a NEC Services Center or  
NEC Pro Care Center to have it replaced.
