Uniden DECT1915 - Manual (Page 56)

Troubleshooting
53
If the fault persists …
Disconnect all other instruments connected to the
same line as the DECT1915/1915+1 and see whether you
can make a call.
Disconnect the base unit from the telephone line and
plug a different phone into the master telephone
socket. Try making a call. If this works, the line is OK.
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. If the call now works, the
adapter may be faulty.
If you cannot make a call, the fault may be on the
exchange line. Contact the service provider.
If you still cannot identify the cause of the problem,
