Caring for your telephone
• Never allow the telephone to come into contact with coloring, oily or aggres-
sive 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 forbidden.
