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 headset doesn’t work at all. • Make sure the power cord is securely plugged in. • Make sure that the battery is securely installed in the cordless headset. • Charge the battery in the cordless headset for at least three hours.
Appendix Troubleshooting • If the previous suggestions do not work, disconnect the telephone base from the telephone jack and connect another phone to that jack. If there is no dial tone on that phone either, the problem is in your wiring or local service. Contact your telephone service provider. The battery does not charge. • Make sure that the battery is securely installed in the cordless headset.
Appendix Troubleshooting • Move the cordless headset closer to the telephone base. You might have moved out of range. • Reset the headset. Power off the headset and then power it on. • Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless headset. Try installing your telephone base as far away as possible from these types of electronic devices. I get noise, static, or a weak signal even when I’m near the telephone base.
Appendix Troubleshooting • If other phones in your home or office are having the same problem, the problem is in your wiring or local service. Contact your telephone service provider (charges may apply). I cannot hear a ring tone from the headset when there is an incoming call. • The headset does not have an external ringer. You can only hear the ring tone when you are wearing the earpiece. • If you have pressed MUTE/FLASH on the headset when it is ringing, it mutes the ring tone of the headset.
Appendix Troubleshooting • Test a working phone at the phone jack. If another phone has the same problem, there may be a problem with the phone jack, wiring or service. Contact your telephone service provider (charges may apply). I hear other calls while using my headset. • Plug a different telephone into the telephone jack that you are currently using. If you still hear other calls, the problem is probably in your building's wiring or local service. Call your telephone service provider.
Appendix Troubleshooting I cannot register the headset. • You must be using a compatible AT&T DECT 6.0 telephone. Visit www.telephones.att.com for a list of compatible telephones. • Your DECT 6.0 telephone has a maximum number of handsets that may be registered to the telephone base. In terms of registration, the telephone base treats a headset like a handset. Refer to your telephone user’s manual for the maximum number of handsets allowed.
Appendix Troubleshooting Common cure for electronic equipment. • If the unit does not seem to be responding normally, try putting the cordless headset in its charger. If it does not fix the problem, do the following (in the order listed): 1. 2. 3. 4. 5. Disconnect the power to the headset charger. Remove the cordless headset battery. Wait a few minutes. Connect the power to the headset charger. Install the battery again, and then place the cordless headset into the headset charger. 6.
