How the Microwave Function Works

Microwaves are a form of energy similar to radio, television waves, and ordinary daylight. This oven has a magnetron that creates microwave energy. Microwaves enter the cooking area through openings inside the oven. They penetrate materials like glass, porcelain, and paper, but cannot pass through metal walls. Microwaves heat food, not the cookware.

A very safe appliance

When the door is opened, the oven automatically stops producing microwaves. Microwave energy is converted completely to heat when it enters food, leaving no "left over" energy to harm you.

Before Use

Unpack your oven and place it on a flat level surface.
Ensure proper ventilation by placing the oven with at least 20 cm of space on top and 10 cm at the rear. Maintain 8 cm from the front edge to prevent tipping.
Plug your oven into an exclusive 230V socket with earth.
Open the door by pulling the handle, place the rotating ring and glass tray.
Fill a microwave-safe container with 300 mL of water and test the oven's operation.

Troubleshooting and error codes

What's wrong when the oven light will not glow?	There may be several reasons why the oven light will not glow. Either the light bulb has blown or the electric circuit has failed.
Does microwave energy pass through the viewing screen in the door?	NO. The holes, or ports, are made to allow light to pass; they do not let microwave energy through.
Why does the BEEP tone sound when a button on the control panel is touched?	The BEEP tone sounds to assure that the setting is being properly entered.
Will the microwave function be damaged if it operates empty?	Yes. Never run it empty.
Why do eggs sometimes pop?	When baking, frying, or poaching eggs, the yolk may pop due to steam build up inside the yolk membrane. To prevent this, simply pierce the yolk before cooking. Never microwave eggs in the shell.
Why is standing time recommended after microwave cooking is over?	After microwave cooking is finished, food keeps on cooking during standing time. This standing time finishes cooking evenly throughout the food. The amount of standing time depends on the density of the food.
Why doesn't my oven always cook as fast as cooling guide says?	Check your cooking guide again to make sure you've followed directions correctly, and to see what might cause variations in cooking time. Cooking guide times and heat settings are suggestions, chosen to help prevent overcooking, the most common problem in getting used to this oven. Variations in the size, shape, weight and dimensions of the food require longer cooking time. Use your own judgment along with the cooking guide suggestions to test food conditions, just as you would do with a conventional cooker.
