Power input varies according to local voltage supply. The density, thickness and moisture 

content of food can affect its cooking time. Ensure all food is piping hot and cooked 

thoroughly before serving. It is essential that food is checked during and after the 

recommended cooking time, even if the auto menu was used.

800W

E

(IEC 60705) 800W is the output power of the 

microwave.

microwave heating categories

Your oven has been tested and labelled to meet the UK government’s voluntary agreement on the 

reheating of pre-cooked food.
The heating characteristics and output power levels of microwave ovens are usually calculated 

using a relatively large portion of food (1000 gram load, IEC 60705) but many packs of precooked 

food are sold in smaller packs, often about 350 grams.
The UK government, in partnership with food companies and microwave manufacturers, have set up 

a system of heating categories to help you choose the reheating time for pre-cooked food.

E is the heating category for your microwave.
Check the cooking times for category E on the 

food’s packaging to see how long it should be 

cooked.

The category, (a letter from A to E) is designed to help you reheat small quantities of food such as 

microwave ready meals.
The label given above and also on the oven door gives the heating category and output power of 

the oven.
Microwave ready meals weighing up to 500g (1lb 2oz) should have cooking instructions for heating 

categories A to E. Follow the instructions for the letter that corresponds to the heating category of 

the oven.
The higher the output power and heating category of the oven the less heating time is required. This 

is shown in the diagrams below:
