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 cleaners containing alcohol, cleaners that corrode plastic or abrasive powders!
