Care of the telephone
• Use either a d amp cloth or an antistatic cloth to
clean the telephone. Never use a dry cloth!
• If the telephone needs to be cleaned thoroughly,
use a neutral, diluted, surface-active cleaning agent.
Ensure that all traces of the cleaning agent are re-
moved with a damp cloth (using water only!).
• Never apply a cleaning agent that contains alcohol or
that is liable to harm plastic surfaces; never use an
abrasive cleaning powder.
