Care of the telephone

• Use either a damp cloth or an antistatic cloth to clean the telephone
set. Never use a dry cloth!
• If the telephone set needs to be cleaned thoroughly, use a neutral, di-
luted, surface-active cleaning agent. Take care that all traces of the
cleaning agent are removed with a damp cloth (using water only!).
• Never apply a cleaning agent which contains alcohol or which is liable
to harm plastic surfaces; never use an abrasive cleaning powder.
