Technical description

5.1 Installation

• Make sure that all packaging materials are removed from the inside of the door.
• Check the microwave oven for damage such as a misaligned or bent door, damaged door seals and sealing surfaces, broken or loose door hinges, and latches and dents  inside or on the door. If you notice any damage, do not put the microwave oven into operation and contact qualified service personnel.
• The microwave oven must be placed on a flat, stable surface that can support its weight as well as the heaviest possible food.
• Do not place the oven near heat, moisture, high humidity or flammable materials.
• Proper operation of the microwave oven requires a sufficient air supply. Keep a sufficient distance (approx. 5 cm) to the outer walls in order to ensure heat exchange. Do  not cover or block openings on the microwave oven. The feet should not be removed.
• Make sure that the connection cable is undamaged and does not run under the microwave oven or across a hot or sharp surface.
• Do not use the microwave oven outdoors.
  ➤ Connect the connection cable of the microwave with a suitable 24 V connection in the vehicle. Make sure that the power supply line is protected by a fuse according to the technical data.

Open and close the door to turn on and use the microwave oven.

6.1 Information on cooking food

• Arrange the food carefully. Place the thickest areas towards the outside.
• Pay attention to the cooking time. Always cook for the shortest indicated time and increase it if necessary. Overcooked foods may smoulder or ignite.
• Cover food during cooking. Covers prevent spraying and ensure even cooking.
• Turn foods such as chicken and hamburger once during the cooking process. Large food such as roasts must be turned over at least once.
• Rearrange foods such as meatballs after half the time from top to bottom and from the centre outwards.

6.2 Information about cookware

• The ideal material for a microwave oven is transparent to microwaves, allowing energy to penetrate through the container and heat the food.
• Microwaves cannot penetrate metal, so metal dishes or dishes with metallic trim should not be used.
• Do not use recycled paper products for cooking in a microwave oven, as they may contain small metal fragments which may cause sparks and/or fires.
• Round/oval dishes are better than square/oblong dishes, because food may overheat in the corners of the dish.
  The following list serves as a guideline for suitable dishes:

6.3 Cooking

| CAUTION! Risk of injury from heated food!

➤ Open the door and remove the heated food.
NOTE
The signal tone is repeated until you open the door. The repetition rate is as follows:

• Two signal tones every ten seconds in the period from 1 second to 60 seconds after heating the food
• Two signal tones every five seconds in the period from 61 seconds to 120 seconds after heating of the food

Cleaning and maintenance

• Turn off the power and unplug the power plug before cleaning.
• Do not use abrasives when cleaning the device.
• Keep the inside of the microwave oven clean. If food splashes or spilled liquids stick to the walls of the microwave oven, wipe them clean with a damp cloth. Use a mild  detergent if the microwave oven is very dirty. Avoid the use of spray and other harsh cleaners, as they may cause stained, streaked or dull surfaces on the door.
• The exterior surfaces should be cleaned with a damp cloth. To prevent damage to the operating parts inside the microwave oven, water should not be allowed to  penetrate directly into the air vents.
• Regularly wipe the door, the door seals and the adjacent parts with a damp cloth to remove soiling or splashes.
• Do not allow the control panel to get wet. Clean it with a soft, damp cloth. Leave the door open to avoid accidentally turning on the microwave oven.
• If moisture accumulates inside or around the outside of the door, wipe it dry with a soft cloth. This can occur if the microwave oven is operated under high humidity  conditions and is normal.
• Odours in the microwave oven can be removed by a cup of water and lemon juice and peels. Pour and place them in a deep microwave-safe container and turn on the  microwave oven for 5 minutes. Wipe it out thoroughly and dry it with a soft cloth.
• Have a defective microwave lamp replaced by a specialist dealer.
• The microwave oven should be cleaned regularly and have any food scraps removed. Not maintaining the device in a clean condition may damage the surface and shorten the service life of the device.
