    Connecting and Setting the Microwave

     

    • 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 microwave 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) from 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.

    Connecting the microwave oven to the power supply.

    • Connect the power plug to the AC mains.
    • The display flashes three times and displays “-: -”.

    Setting the time

    • Press the CLOCK button to set the time.
    • The display shows 00:00.
    • Press the + or – buttons to set the hours.
    • Press the CLOCK button.
    • Press the + or – buttons to set the minutes.
    • Press the CLOCK button or wait 5 seconds to save the time

    Operation

    • 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 produce smoke or catch fire.
    • Cover food during cooking. Covers prevent splashing and ensure uniform cooking.
    • Turn foods such as chicken and hamburger once during the cooking process. Large foods 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 center outwards.
    • The ideal material for a microwave oven is permeable to microwaves, allowing energy to penetrate 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 that 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.
