If food packaging gives cooking instructions based on IEC Power ratings, set cooking times according to the IEC Power of your oven. For example : If the cooking instructions are based on a 650 W oven, then you will need to reduce some cooking time for t he 850 W Ready meals are now very convenient and popular. These are meals which are already prepared and cooked by the food manufacturer, and then frozen, chilled or vacuum sealed for long life. Increasingly, heating times for such ready meals are being based on the Heating Categories A, B, C, D and E. On this instance, simply match the heating category of your oven to the instructions on the food package, and set your timer accordingly. For example : If the heating instructions are 3 minutes on HIGH for a D category oven, then you will need to set your timer for less than 3 minutes on HIGH for the GK640-E (E category). Always remember that cooking instructions are intended only as a guide. If you have followed the instructions and the food is still not piping hot throughout, simply return it to the oven and cook it until it is.

CARE OF YOUR MICROWAVE OVEN

Cleaning the Microwave Oven

1. Unplug the oven from the electrical socket before cleaning.

2. Clean the inside of the oven. Wipe up all spills with a damp cloth. Kitchen

detergent solution may be used if the oven gets too dirty. Do not use harsh detergents or abrasives.

3. Clean the outside of the oven with soap and water, then dry with a soft cloth.

4. When you clean the window of the door, be sure to use a soft cloth after washing

with very mild soap and water. Do not use window cleaner as the front door can be scratched by harsh soap or cleaners. If food remnant or spilled liquids stick to the oven walls, or between door seal and door surface, they will absorb microwaves possibly resulting in arcing or sparks. Make sure that water does not get into the back ventilation or control panel opening. CAUTION GK640-E_GK641-E_XEU_DE68-04279B-01_EN.indd 21 2014-06-27 6:49:54English - 22

Lamp Holder Lamp (230 V 25 W) Outer Panel Lamp Cover cookware guide To cook food in the microwave oven, the microwaves must be able to penetrate the food, without being reflected or absorbed by the dish used. Care must therefore be taken when choosing the cookware. If the cookware is marked microwave-safe, you do not need to worry. The following table lists various types of cookware and indicates whether and how they should be used in a microwave oven. Cookware Microwave- safe Comments Aluminum foil

Can be used in small quantities to protect areas against overcooking. Arcing can occur if the foil is too close to the oven wall or if too much foil is used. China and earthenware

Porcelain, pottery, glazed earthenware and bone china are usually suitable, unless deco- rated with a metal trim. Disposable polyester cardboard dishes

Some frozen foods are packaged in these dishes. Fast-food packaging

Can be used to warm food. Overheating may cause the polystyrene to melt.
