SEVERIN MW 7920 Mode D'emploi page 14

Before first use
∙ After unpacking and every time before connecting the unit to the power supply,
check the unit and its power cord carefully for any signs of damage.
∙ Warning! Ensure that the door, including the inspection window, door seals and
locks, are not damaged or bent and that it closes firmly against the support. This
is important to ensure that no microwave energy is allowed to escape during
operation. For the same reason, the entire casing as well as the inside of the oven
must be carefully checked.
Should the unit show any signs of damage, it must not be used under any
circumstances until it has been repaired by a qualified technician.
∙ Remove any exterior and interior packaging materials. The nameplate must not be removed. All these materials are
suitable for recycling.
∙ Caution: Keep any packaging materials well away from children – such materials are a potential source of danger, e.g.
of suffocation.
∙ Before the appliance is used for the first time, or after extended periods of non-use, it should be thoroughly cleaned as
described in the section Cleaning.
∙ Note: Do not switch the unit on unless the food to be heated or cooked has been placed inside the oven.
Operating the appliance empty could result in damage to the unit.
ISM Device
This product is an ISM device of Group 2 Class B. Group 2 includes all ISM devices (industrial, scientific, medical), as well
as spark-erosion devices, in which radio frequency energy is generated and/or is utilised in the form of electromagnetic
radiation for processing materials. Class B are devices for household use or devices on power supply networks that feed
residential buildings.
The microwave function (Group II in compliance with EN 55011)
Electromagnetic energy is generated inside the unit, causing the molecules in the food (mainly water molecules) to oscillate
and subsequently causing the food to become hot. Food with high water content will therefore heat up faster than relatively
dry food. The heat is generated gradually inside the food. Any utensils, container or plates used are heated up only indirectly
as a result of the food temperature.
∙ Do not place the food to be cooked directly on the glass turntable, but use suitable dishes. The dishes must not extend
beyond the glass turntable.
∙ Metal objects are to be avoided since microwaves are reflected from metal surfaces and might not reach the food to be
cooked. Any metal in the oven could also cause sparks, resulting in possible damage to the unit.
∙ As a general rule, cutlery or metal containers must not be used in the microwave oven. Some food wrappings contain
aluminium foil or wires underneath a layer of paper and are therefore also unsuitable for use with microwave appliances.
Should the use of aluminium foil be recommend in a recipe, ensure that the food is tightly wrapped in the aluminium foil
(avoiding any air blisters). Ensure a minimum distance of 2.5 cm between the aluminium foil and the interior walls of the
oven.
∙ Always make sure that the cooking container or plate used does not contain any metal decoration such as a gold rim or
colour containing metal particles. Lead crystal objects are also not suitable. Always make sure that no parts of the cooking
containers used are hollow (e.g. the handles). Porous materials may have absorbed water during cleaning and are again
not suitable. Cooking containers or utensils made of 'Melamine' plastic material absorb energy and are also unsuitable.
∙ Containers made from heat-resistant glass or porcelain are well suitable for use in microwave appliances.
∙ Plastic is suitable only if it is heat-resistant.
∙ Cooking bags etc. should be punctured to be able to release any high pressure during cooking.
∙ Plastic cooking containers especially designed for use with microwave ovens are available at most kitchenware dealers.
