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.
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.
Do not place the oven where heat, moisture, or high humidity are generated, or near combustible
materials.
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.
Do not operate the oven without glass tray, roller support, and shaft in their proper positions.

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.

or vapors in this appliance. This type of oven is specifically designed to heat and cook food and for
domestic use only.
Do not operate the oven when empty.
Do not operate this appliance if it has a damaged cord or plug, if it is not working properly or if it has been
damaged or dropped. If the supply cord is damaged, it must be replaced by the manufacturer or its
service agent or a similarly qualified person in order to avoid a hazard
Children or infirm persons without adequate supervision should not operate this MWO.
Young children should be supervised to ensure that they do not play the appliance. .
Place the cookware in the cavity along with a glass half full of water..Heat on 900 W (100%) for one
minute. If the cook ware 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 for microwave cooking.
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.
WARNING: Liquid or other food must not be heated in sealed containers since they are liable to explode.
Microwave heating of beverage can result in delayed eruptive boiling, therefore care has to be taken when
handle the container.
Do not fry food in the oven. Hot oil can damage oven parts and utensils and even result in skin burns.
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.
Pierce foods with heavy skins such as potatoes, whole squashes, apples and chestnuts before cooking.
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.

Watch cooking time. Cook for the shortest amount of time indicated and add more as needed. Food
severely overcooked can burn or ignite.
Cover foods while cooking. Covers prevent spattering and help foods to cook evenly.
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.
Rearrange foods such as meatballs halfway through cooking both from top to bottom and from the center
of the dish to the outside.

The ideal material for a microwave utensil is transparent to microwave, it allows energy to pass through
the container and heat the food.
Microwave can not penetrate metal, so metal utensils or dishes with metallic trim should not be used.
Do not use recycled paper products when microwave cooking, as they may contain small metal fragments
which may cause sparks and/or fires.
Round /oval dishes rather than square/oblong ones are recommend, as food in corners tends to
overcook.
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.

Turn off the oven and remove the power plug from the wall socket before cleaning.
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.
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.
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.
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.
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.
It is occasionally necessary to remove the glass tray for cleaning. Wash the tray in warm sudsy
water or in a dishwasher.
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.
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.
When it becomes necessary to replace the oven light, please consult NEC Service Center or
NEC Pro Care Center to have it replaced.
