at all.
There is no dial
tone
Make sure the power adapter is securely plugged into
an outlet not controlled by a wall switch.
Make sure the telephone line cord is plugged firmly
into the telephone base and the modular wall jack.
Unplug the telephone’s electrical power. Wait for
approximately 15 seconds, then plug it back in. Allow
up to one minute for the telephone to synchronize.
Disconnect the telephone base from the telephone
line wall jack and plug in a working telephone. If this
telephone does not work, the problem is probably in
the wiring or the local service. Call the local telephone
company.
First, try all the above suggestions. Also inspect the
coiled handset cord connections at both ends.
The telephone line cord might be malfunctioning. Try
installing a new telephone line cord.
Disconnect the telephone base from the telephone jack
and connect a different telephone. If there is no dial tone
on the telephone either, the problem is in your wiring or
local service. Contact your local telephone company.
Make sure HOLD is not pressed.
If there is no dial tone when the HEADSET key is
pressed, make sure the headset is firmly connected in
the headset jack.
First, try all the above suggestions in the There is no
dial tone section.
Make sure there is a dial tone before dialing. It is
normal if the telephone takes a second or two to
synchronize before producing a dial tone. Wait an extra
second before dialing.
Check that all the telephones connected to the same
telephone line are hung up.
If the other telephones in your home are having
the same problem, the problem is in the wiring or
local service. Contact your local telephone company
(charges may apply).
