• Do not block or obstruct air vent openings.
• Do not place objects on top of the oven.

Microwave and Grill Power Levels

The oven offers 9 microwave and grill power levels. The microwave power level is controlled by the pulsing of microwave energy. You will hear the pulsing when using levels other than HIGH.

General Recommendations:

• High (100 P): For fast cooking or reheating (e.g., casseroles, beverages, vegetables).
• Med High (70 P): For longer cooking of dense foods (e.g., roast joints, meat loaf, plated meals) and sensitive dishes (e.g., sponge cakes). Ensures even cooking without overcooking sides.
• Med (50 P): For dense foods requiring long conventional cooking times (e.g., beef casserole) to ensure tenderness.
• Med Low/Defrost (30 P): Ideal for defrosting evenly. Also suitable for simmering rice, pasta, dumplings, and cooking egg custard.
• Low (10 P): For gentle defrosting (e.g., cream gateaux, pastry).

Combination Settings:

Notice: Ensure the oven power is switched off (timer to "0") when removing food. Operating the microwave oven without food can result in overheating and damage to the magnetron.

Warnings:

• Ensure the TIMER/ DEFROST GUIDE is returned to "0" at the end of cooking, or the oven may start automatically when the door is closed.
• If food is cooked beyond the standard time at 100 P, the oven power will automatically reduce to prevent overheating.

Defrosting Guide

This guide helps defrost specific foods like chicken portions, chops, fish, minced meat, and sausages.

Example: To defrost 0.4 kg of chicken portions:

• 1. Place chicken portions in a flan dish on the turntable.
• 2. Set MICROWAVE POWER CONTROL knob to DEFROST (MEDIUM LOW).
• 3. Set TIMER/ DEFROST GUIDE to 0.4 kg. The oven starts immediately. Turn chicken portions over 1-2 times during defrosting.
• 4. After defrosting, cover food in foil and let it stand until thoroughly defrosted.

Note: Defrosting times are based on standard conditions; adjust as necessary based on results.

Suitable Ovenware

For microwave cooking/defrosting, energy must pass through the container to the food. Choose cookware accordingly. Round/oval dishes are preferable to square/oblong ones as food in corners can overcook.

WARNING: When heating food in plastic or paper containers, monitor the oven due to the risk of ignition.

Care and Cleaning

General Cautions:

• DO NOT USE COMMERCIAL OVEN CLEANERS, STEAM CLEANERS, ABRASIVE, HARSH CLEANERS, OR ANYTHING CONTAINING SODIUM HYDROXIDE OR SCOURING PADS ON ANY PART OF YOUR MICROWAVE OVEN.
• Clean the oven at regular intervals and remove food deposits. Failure to keep the oven clean can lead to surface deterioration, adversely affecting the appliance's life and potentially causing a hazardous situation.

Oven Interior Cleaning:

• 1. Wipe splatters or spills with a soft damp cloth or sponge after each use while the oven is still warm.
• 2. For heavier spills, use mild soap and wipe several times with a damp cloth until residues are removed. Do not remove the waveguide cover.
• 3. Ensure mild soap or water does not penetrate small vents in the walls, which may cause damage.
• 4. Do not use spray cleaners on the oven interior.
• Keep the waveguide cover clean at all times. It is constructed from fragile material and requires careful cleaning.
• NOTE: Excessive soaking may cause disintegration of the waveguide cover. The waveguide cover is a consumable part and may need replacement if not cleaned regularly.

Oven Exterior Cleaning:

Clean the outside with mild soap and water. Wipe off soap with a moist cloth, and dry the exterior with a soft towel.

Control Panel Cleaning:

Open the door before cleaning to deactivate the control panel. Use only a cloth dampened with water to gently wipe the panel. Avoid excessive water or any chemical/abrasive cleaners.

CAUTION:

Take care not to move the TIMER knob from "0" (off) position during cleaning, or the oven will start as soon as the door is closed.

Turntable and Turntable Support Cleaning:

Remove the turntable and turntable support. Wash in mild soapy water and dry with a soft cloth. Both are dishwasher safe.

Door Cleaning:

Clean both sides of the door, seals, and adjacent parts with a soft, damp cloth. Do not use abrasive cleaners.

NOTE:

A steam cleaner should not be used.

Cleaning Tip:

For easier cleaning, place half a lemon in a bowl with 300 ml (1/2 pint) water. Heat for 10-12 minutes. Wipe the oven clean with a soft, dry cloth.

Troubleshooting

Perform these simple checks before calling for service:

Place half a cup of water on the turntable, close the door, and set the oven to cook for 1 minute. Check:

• 1. Does the oven lamp come on?
• 2. Does the turntable rotate?
• 3. Does the cooling fan work? (Check by placing your hand above the air vent openings.)
• 4. Does the audible signal sound after 1 minute?
• 5. Is the water in the cup hot?
• 6. Does the grill heating element become red after 3 minutes?

If you answer "NO" to any question, first check if the oven is plugged in and the fuse has not blown. If these are okay, consult the troubleshooting chart.
