fitted correctly.
The batteries might need
replacing.
Adjust the contrast on your
display, see page 10.

Check that the ringer is not
switched off on the phone that
is connected to your Caller
Display 1000.
Check that no other connected
phones are off the hook.
Your Caller Display 1000
checks the content of the caller
message it receives. If it
detects a problem with a
message it displays NO NUMBER
rather than risk leaving a
message with a possible
mistake. This does not mean
that your Caller Display 1000 is
faulty.
If you continually receive NO
NUMBER, call BT free of charge on
customers or
for business customers, or your
service provider.
