Caring for your telephone
• Never allow the telephone to come into contact with colouring, 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 cleaners containing alcohol, cleaners that corrode plastic or
abrasive powders!
