Troubleshooting
If you have difficulty with your telephone, please try the suggestions below. 
For customer service, visit our website at www.telephones.att.com or 
call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268.
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.
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 telephone 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 into 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 14).
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 
telephone 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.
