Cleaning the Unit
The unit must be disconnected from the power supply by pulling out the mains
plug if cleaning the unit involves using liquids.
The unit surfaces can be cleaned using a dry cloth.
If the unit is very dirty, it may be cleaned with a damp cloth which has been
dipped in a mild water soluable detergent and well drained. Make sure that no
liquid gets inside the unit and keep moisture away from the connection sockets
at the rear of the unit.
Never use abrasive cleansers or solvents!
