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 doesnt work at all. Make sure the power cord is securely plugged in. Make sure the battery is securely installed in the cordless headset. Make sure the telephone line cord is securely and firmly plugged into the headset or telephone base and the telephone wall jack. Charge the battery in the cordless headset for at least 6 hours. For optimum daily performance, return the cordless headset to its charger when not in use. Reset the headset. Power off the headset and then power it on. Reset the headset base or charger. Unplug the units electrical power. Wait for approximately 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and headset base or charger to reset. You may need a new battery. Please refer to page 7 of this users manual. I cannot get a dial tone. Try all the suggestions above. Move the cordless headset closer to the headset or telephone base. You might have moved out of range. If the previous suggestions do not work, disconnect the headset or telephone base from the telephone jack and connect a different phone. If there is no dial tone on that phone either, the problem is in your wiring or telephone service. Contact your telephone service provider. Your telephone line cord might be defective. Try installing a new telephone line cord. 27 Appendix Troubleshooting I am getting a buzzing sound on my headset or corded base speakerphone. Your telephone may experience interference from the headset. To overcome this problem, move the headset base at least 12 inches away from the telephone. Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your headset as far away as possible from these types of electronic devices. I cannot dial out. Try all the suggestions above. Make sure you have a dial tone before dialing. The cordless headset may take a second or two to find the headset or telephone 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. If you cannot eliminate background noise, try dialing from another room with less background noise. If the other phones in your home are having the same problem, the problem is in your wiring or local service. Contact your telephone service provider (charges may apply). The other party cannot hear my voice during a call. If you registered the accessory cordless headset to a headset base, try adjusting the speaking volume setting on the headset base. See the volume section of the users manual for your headset base model TL7610/TL7611/TL7612 for additional troubleshooting. Visit www.telephones.att.com/manuals to view or download the user manuals. 28 Appendix Troubleshooting My cordless headset isnt performing normally. Make sure the power cord is securely plugged into the headset base or charger. Plug the unit into a different, working electrical outlet not controlled by a wall switch. Move the cordless headset closer to the headset or telephone base. You might have moved out of range. Reset the headset base or charger. Unplug the units electrical power. Wait for 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and headset base or charger to reset. Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your headset as far away as possible from these types of electronic devices. I want to use my headset with a different headset base or cordless telephone. You need to deregister (see pages 25-26) the headset from the current headset or telephone base and then register (see pages 9-11) it to a new headset base or cordless telephone. 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 or charger and the ON/OFF light on the headset does not come on, refer to The ON/OFF light on the headset is off while charging in this Troubleshooting guide (page 32). Charge the battery in the cordless headset for at least 6 hours. For optimum daily performance, return the cordless headset to the headset or charger when not in use. 29 Appendix Troubleshooting You may need a new battery. Please refer to the Battery charging section on page 8. Your headset might be defective. Please refer to the Limited warranty section on pages 45-48 for further instructions. I get noise, static, or weak signal even when Im near the headset or telephone base. If you subscribe to high-speed Internet service (DSL - digital subscriber line) through your telephone lines, 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. Please contact your DSL service provider for more information about DSL filters. You may be able to improve the performance of your cordless headset by installing your new headset base farther from any other existing cordless telephone system. Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your headset as far away as possible from these types of electronic devices. Do not install this headset near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating. If your headset is plugged in with a modem or a surge protector, plug the headset (or modem/surge protector) into a different location. If this doesn't solve the problem, relocate your headset or modem farther apart from one another, or use a different surge protector. Relocate your headset or telephone base to a higher location. You may experience better reception by elevating the headset or telephone base. If the other phones in your home are having the same problem, the problem is in your wiring or telephone service. Contact your telephone service provider (charges may apply). 30 Appendix Troubleshooting I hear other calls while using my headset. Disconnect the headset or telephone base from the telephone jack, and plug in a different telephone. If you still hear other calls, the problem is probably in your buildings wiring or local service. Call your telephone service provider. 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. 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. The layout of your home or office might be limiting the operating range. Try moving the headset or telephone base to another location, preferably on an upper floor. Test a working phone at the phone jack. If another phone has the same problem, the problem is the phone jack, wiring or service. Contact your telephone service provider (charges may apply). Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your headset as far away as possible from these types of electronic devices. Install the battery again, and place the cordless headset in the headset base or charger. Wait for the cordless headset to reestablish its connection with the headset or telephone base. Allow up to one minute for this to take place. Your telephone line cord might be defective. Try installing a new telephone line cord. 31 Appendix Troubleshooting My calls cut in and out while Im using my cordless headset. Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your headset as far away as possible from these types of electronic devices. Do not install this headset near a microwave oven or on the same electrical outlet. You may experience decreased performance while the microwave oven is operating. If your headset is plugged in with a modem or surge protector, plug the headset (or modem/surge protector) into a different location. If this doesn't solve the problem, relocate your headset or modem farther apart from one another, or use a different surge protector. Relocate your headset or telephone base to a higher location. You may experience better reception by elevating the base. If the other phones in your home are having the same problem, the problem is in your wiring or local service. Contact your telephone service provider (charges may apply). 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 charger until the ON/OFF light on the headset turns on. Unplug the units electrical power. Wait for 15 seconds, then plug it back in. Allow up to one minute for the cordless headset and headset base or charger to reset. Clean the cordless headset and headset base or charger charging contacts each month using a pencil eraser or cloth. 32 Appendix Troubleshooting Your headset or headset base might be defective. Please refer to the Limited warranty section on pages 45-48 for further instructions. I cannot register the headset. For registration to a cordless telephone:

You must be using a compatible AT&T DECT 6.0 cordless telephone. Visit www.telephones.att.com/headsets for a list of compatible telephones.
