Telephone Maintenance
• 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 cleansing agent containing surfactants,
such as dishwashing liquid. Afterwards remove all traces of the cleansing agent with a damp
cloth moistened with water only.
• Never use cleaners containing alcohol, cleaners that corrode plastic, or abrasive powders.
