AEG Eclipse 15 - Persistent Faults

15.7 If the fault persists...
tDisconnect all other instruments connected to the same line and try to make a call.
tDisconnect the base unit from the telephone line and plug a different phone. Try making a call. If this
works, the line is OK.
tIf the call does not work and you are using a two-way socket adapter, remove it and plug a telephone
directly into the socket.
tIf the call now works, the adapter may be faulty.
tIf you cannot make a call, the fault may be on the exchange line. Contact the service provider.
