Appendix 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. • 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. 61
