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 cleaning fluids containing alcohol or plas-
tic-damaging detergents to clean the telephone.
The use of scouring agents is also forbidden.
