• All surfaces, including the microwave’s door, can remain hot after operation. Take care to avoid touching the waveguide cover or other hot surfaces.
• Containers and cookware may become hot because of heat transferred from the heated food. Potholders may be required.
• Liquids and food should not be heated in sealed containers because they could explode.
• Heating liquids can lead to a delayed sudden eruption of scalding liquid, so use care when handling the container.
• Liquids, such as water, coffee, or tea are able to be overheated beyond the boiling point without appearing to be boiling. 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 THE CONTAINER IS DISTURBED OR A UTENSIL IS INSERTED INTO THE LIQUID.
• Do not fry food in the microwave. Hot oil can damage microwave parts and cause burns.
• Peel or poke holes in food with hard skins such as potatoes, sausages, and chestnuts before heating so steam can escape.
• Eggs in the shell and hard-boiled eggs should not be heated in the microwave since they may explode even after heating has ended.
• The contents of baby bottles and baby jars should be stirred or shaken, and the temperature should be checked before consumption.
• Remove wire twist-ties from paper or plastic bags before placing bag in oven.

Use these techniques for the best results:

• Arrange the food carefully. Place the thickest portion of the food toward the outside.
• Always cook for the shortest indicated time and increase it if necessary. Overcooked foods may produce smoke or catch fire.
• Cover food during cooking. Covers prevent splashing and ensure uniform cooking.
• Turn food over after half the cooking time has expired.
• Rearrange foods such as meatballs from top to bottom and from the center outwards after half the cooking time has expired.

• NOTICE: To prevent damage to the turntable, do not place hot foods or cookware on a cold turntable, and do not place frozen foods or cookware on a hot turntable.
• NOTICE: Do not allow the cookware to touch the interior walls during operation.
• NOTICE: When using a browning dish, always place a heat-resistant insulator such as a heat-resistant ceramic plate under the dish to prevent damage to the turntable and turntable ring.
• i (Informational): A new microwave oven can cause odors due to production residues. Ventilate the living space when using the microwave oven the first few times. Heating a cup of water at high power multiple times is recommended to eliminate odors.
