4. Operating Instructions
Control Panel Overview:
- Upper Dial (Time/Defrost): Used to set the cooking time (up to 30 minutes) or select defrost by weight.
- Lower Dial (Power Level): Used to select the desired cooking power level (Low, M.Low, Med, M.High, High).
Basic Microwave Cooking:
- Place the food in a microwave-safe container on the glass turntable. Close the door securely.
- Turn the Lower Dial (Power Level) to select the desired power setting. For most cooking, 'High' is suitable.
- Turn the Upper Dial (Time/Defrost) to set the desired cooking time. The oven will start automatically once the dial is turned.
- When the set time expires, the oven will automatically stop and a bell will sound.
- Carefully remove the food. Always use oven mitts as the container and food may be hot.
Defrosting:
The Harper HMO200 offers defrosting by time or by weight.
- Defrost by Time: Place the frozen food in the oven. Turn the Lower Dial (Power Level) to 'Low' or 'M.Low'. Turn the Upper Dial (Time/Defrost) to the desired defrosting time.
- Defrost by Weight: Place the frozen food in the oven. Turn the Upper Dial (Time/Defrost) to the appropriate weight setting indicated on the dial (e.g., 0.2kg, 0.5kg, 1.0kg). The oven will automatically calculate the defrosting time.
During defrosting, it is recommended to turn the food over periodically for more even results.
