My telephone
appears to be dead.
Make sure the power adapter is securely plugged into
an electrical outlet not controlled by a wall switch.
Unplug the power adapter from the electrical outlet.
Wait for approximately 15 seconds, then plug it in
again. Allow up to one minute for the telephone to
synchronize.
Disconnect the telephone base from the telephone
wall jack and plug in a working telephone. If this
telephone does not work, the problem is probably
in the wiring or the telephone service. Call the
telephone service provider.

There is no dial tone. First, try all suggestions in My telephone appears

The telephone line cord might be malfunctioning. Try
installing a new telephone line cord.
Make sure the coiled handset cord is securely installed
between the handset and the telephone base.
Disconnect the telephone base from the telephone
wall jack and connect a different telephone. If there
is no dial tone on that telephone either, the problem
is in your wiring or telephone service. Contact your
telephone service provider (charges may apply).
