Important Safety Instructions
VOLTAGE AND POWER WARNING
The voltage used must be the same as specified on the microwave
oven. Using another voltage than that which is specified is dangerous,
and may result in a fire or other type of accident causing damage.
Do not plug your oven in via an extension cable as this can be
dangerous. It is important to plug the oven directly into a wall socket.
The back of the appliance heats up during use. Do not allow the cord to
be in contact with the back of the appliance or cabinet surface.
PLACEMENT OF THE OVEN
Locate the oven on a surface which is flat and stable. Do not place
the oven in a hot or damp place; e.g. near a gas or electric range. Do
not operate the oven when the room temperature is higher than 40°C
and/or the humidity is more than 85%. Free airflow around the oven is
important.
There is a possibility of a small amount of interference with weak
broadcast signals if the microwave oven is too close to a radio or TV.
For safe and efficient operation, the oven must have sufficient air flow
to the air vents i.e. 5 cm at both sides and rear, and 20 cm at the top.
This microwave oven requires free airflow in the back for maximum
cooling efficiency. You should keep the air vents clear while cooking.
Do not install appliances at higher than 1.6 m and also, less than 0.8 m.
Oven must be placed for easy access to control panel and door and
also, for disconnect power or shut off power by fuse or circuit breaker.
An external equipotential bonding conductor is provided at the back
side of the oven and it is marked by this symbol.
