Registration and de-registration
Adding and registering headset to telephone
To register the headset to an AT&T DECT cordless telephone base:
1.
2.
3.
4.
5.
You must de-register the headset from the headset base (see page 34).
Make sure the battery is properly installed in the headset (see page 12). The ON/OFF light flashes twice every five seconds to indicate the headset is not registered.
Place the headset in the headset base and allow it to charge for at least five minutes before beginning registration. Leave the headset in the base while registering the headset.
On the telephone base of the cordless phone, press and hold the HANDSET
LOCATOR button until the IN USE light comes on (about four seconds) and release the button.
The headset is registered to the telephone base automatically; this may take about 30 seconds to complete. The IN USE light on the telephone base turns off. The headset
ON/OFF light turns blue on the first headset registered. The headset ON/OFF light turns orange on the second headset registered. To verify registration was successful, press the headset ON/OFF button and check for a dial tone.
NOTE: If the registration is not successful, the ON/OFF light on the headset flashes twice every five seconds. Reset the headset and try again. Remove the headset from the base and press ON/OFF. Then place the headset back into the headset base. Try the registration process again.

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 can cause interference to your cordless headset.
Try installing your headset as far away from these types of electronic devices as possible: television sets, VCRs, or other cordless telephones.

Maintenance and Troubleshooting
Troubleshooting
I cannot dial out.
• First 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 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 the 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 local telephone company (charges may apply).
The other party cannot hear my voice during a call.

Maintenance and Troubleshooting
Troubleshooting
I get noise, static, or weak signal even when I’m near the headset base.
• If you subscribe to high-speed Internet service (digital subscriber line - DSL) 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 as far as possible from any existing cordless telephone system.
• Other electronic products can cause interference to your cordless phone. Try installing your phone as far away from the following electronic devices as possible: television sets, VCRs, or other cordless telephones.
• 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, re-locate your headset or modem farther apart from one another, or use a different surge protector.

• Relocate your headset base to a higher location. You may experience better reception by elevating the headset base.
• If the other phones in your home are having the same problem, the problem is in your wiring or local service. Contact your local telephone company (charges may apply).
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 local service. Call your local telephone company.
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
TL7000 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.
• The layout of your home or office might be limiting the operating range. Try moving the headset base to another location, preferably on an upper floor.
