Appendix Troubleshooting If you have difficulty with your headset, please try the following suggestions. 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 headset doesn't work at all. • Make sure the power cord is securely plugged in. • Make sure the battery connector is securely plugged into the cordless headset.
Appendix Troubleshooting I cannot get a dial tone. • First, try all the suggestions, as mentioned above. • Move the cordless headset closer to the headset base. You might have moved out of range. • If you are using LIFTER MODE, you might need to slide the LIFTER AUDIO ADJUST switch (page 17). • If the previous suggestions do not work, disconnect the headset base from the telephone jack and connect a different phone.
Appendix Troubleshooting I cannot dial out. • First, try all the suggestions, as mentioned above. • Make sure you have a dial tone before dialing. The cordless headset may take a second or two to find the headset base and produce a dial tone. This is normal. Wait an extra second before dialing. • Eliminate any background noise. Noise from a television, radio or other appliances may cause the headset to not dial out properly.
Appendix Troubleshooting My cordless headset isn't performing normally. • Make sure the power cord is securely plugged into the headset base. Plug the unit into a different working electrical outlet not controlled by a wall switch. • Move the cordless headset closer to the headset base. You might have moved out of range. • Reset the headset base. Unplug the unit's electrical power. Wait for 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and headset base to reset.
Appendix Troubleshooting The batteries do not hold a charge. • Make sure that the headset battery is installed and securely plugged into the connector. • If the cordless headset is in the headset base and the ON/OFF light on the headset does not turn on, refer to The ON/OFF light on the headset is off while charging on page 44 of this Troubleshooting guide. • Charge the battery in the cordless headset for at least 6 hours.
Appendix Troubleshooting I get noise, static, or weak signal even when I'm near the headset base. • If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone line, you must install a DSL filter between the telephone line cord and the telephone wall jack. The filter prevents noise and caller ID problems caused by DSL interference. Contact your DSL service provider for more information about DSL filters.
Appendix Troubleshooting I hear other calls while using my headset. • Disconnect the headset base from the telephone jack, and plug in a different telephone. If you still hear other calls, the problem is probably in your building's wiring or telephone service. Contact your telephone service provider. My calls cut in and out while I'm using my cordless headset. • Other electronic products such as HAM radios and other DECT phones, can cause interference with your cordless headset.
Appendix Troubleshooting I cannot hear a ring tone from the headset when there is an incoming call. • If you have pressed MUTE/FLASH on the headset when it is ringing, it mutes the ring tone of the headset. The ring tone resumes on the next call. • If you are using a handset lifter, see the TL7100 handset lifter user's manual. • You may have too many extension phones on your telephone line to allow all of them to ring simultaneously. Try unplugging some of the other phones.
Appendix Troubleshooting The ON/OFF light on the headset is off while charging. • Make sure the power and line cords are plugged in correctly and securely. • Make sure that the battery connector is securely plugged into the cordless headset. • Push the headset downwards in the headset base charging cradle until the ON/OFF light on the headset turns on. • Unplug the unit's electrical power.
