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 18). • 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.
