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 remove 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 for-
bidden.
