Caring for your telephone
• Never allow the telephone to come into contact with coloring,
oily or aggressive agents.
• Always use a damp or antistatic cloth to clean the telephone.
Never use a dry cloth.
• If the telephone is very dirty, clean it with a diluted neutral cleaner
containing surfactants, such as a dish detergent. Afterwards re-
move all traces of the cleaner with a damp cloth (using water
only).
• Never use aggressive or alcohol-based cleansers on plastic
parts. The use of scouring agents is also forbidden.
