Care of the telephone
• Use either a damp 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 removed 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.
Troubleshooting
There is no response after a key has been pressed:
Check whether the key has become stuck.
No ringing tone when an incoming call is received:
Check whether you have activated the Do Not Disturb function Æ page 70.
If you have, cancel this function to receive calls again.
You cannot dial a number:
Check whether you have locked the telephone Æ page 72. If you have, un-
lock the telephone to make calls again.
The time shown on the display is not correct:
After 24 hours at the latest, the time is corrected automatically (overnight).
All other faults:
First contact the service personnel. If the fault cannot be
eliminated, Customer Service must be called in.
