• Remove and re-install the battery.

The telephone does not ring when there is an incoming call.

Make sure the ringer is on (page 14).

Make sure the telephone line cord(s) and the power adapter are plugged in properly (see the installation guide).

There may be too many extension telephones on the telephone line to allow all of them to ring simultaneously. Try unplugging one phone at a time until the phones start ringing.

Test a working telephone at the same telephone jack. If another telephone has the same problem, the problem is in the telephone jack. Contact your local telephone company (charges may apply).
