the problem, try resetting the security

try to use the handset
The handset and base are not
communicating properly. You might
be out of range while attempting to
dial. Move closer to the base and try

does not help, the handset and base

To reset the security code, try
the following:

check to make sure the CHARGING
light is on. Wait 15 seconds, then
pick up the handset and press

If you have no dial tone, check all the
