Fixing Problems

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 con-
taining 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 plastic-damaging deter-
gents to clean the telephone. The use of scouring agents is also forbid-
den.
