My telephone does not work at all.
Make sure the power adapter is securely plugged into an electrical outlet
not controlled by a wall switch.
Make sure you plug the telephone line cord securely and firmly into the
telephone jack and the telephone wall jack.
Unplug the power adapter from the electrical outlet. Wait for
approximately 15 seconds, then plug it back in. Allow up to one minute for
the telephone to reset.
You may need to purchase three AA alkaline batteries as backup batteries
to make the telephone work in the event of a power failure. Please refer
to
optional backup battery installation on page 4 in this user’s manual.
Disconnect the telephone base from the telephone wall jack and plug in a
working telephone. If that telephone does not work, the problem is probably
in the wiring or the local service. Call your telephone service provider.
I cannot get a dial tone.
First, try all suggestions above.
Make sure you plug the handset cord securely and firmly into the handset
jack on the telephone base and the corded handset.
Your telephone line cord might be malfunctioning. Try installing a new
telephone line cord.
Make sure
hoLD is not pressed.
If there is no dial tone when the hEADSET key is pressed, make sure a
corded headset is firmly connected in the headset jack.
If you are only using one telephone line, make sure to set it as the primary
line (see
Set the primary line on page 18).
If the previous suggestions do not work, disconnect the telephone base
from the telephone jack and connect to a different telephone. If there
is no dial tone on that telephone either, the problem is in your wiring or
local service. Contact your telephone service provider.
I cannot dial out.
First try all the suggestions above.
Make sure there is a dial tone before dialing. The telephone might take a
second or two to produce a dial tone. This is normal. Wait an extra second
before dialing.
Check that all the telephones connected to the same telephone line are
hung up.
