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.
