Registration and deregistration Adding and registering handsets Before using a new CL80121 handset, you must register it with the AT&T CL82311 telephone system (purchased separately). The telephone system can support up to 12 handsets. The handsets provided with your telephone system are already registered as HANDSET 1 and so forth. Additional handsets registered to the telephone system are assigned in sequential order they are registered (up to HANDSET 12). You must register each handset separately.
Registration and deregistration Adding and registering handsets If registration fails, the system will automatically try to register again. If registration fails after the third try, Registration failed appears on the screen for a few seconds. This may take up to five minutes to occur. Please start again from Step 1 on the previous page. NOTES: • You cannot register a handset if any other system handset is in use.
Registration and deregistration Deregistering handsets You may need to deregister your handsets if: • You have 12 registered handsets and need to replace a handset. -OR• You wish to change the designated handset number of your registered handsets. You must first deregister ALL the handsets, and then register each handset you wish to use again, one at a time. Please read carefully through all the instructions on this page before beginning the deregistration process.
Appendix Troubleshooting If you have difficulty with your phone, 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. The handset registration is unsuccessful. • Follow the handset registration instructions to register the handset again (see Adding and registering handsets on pages 8-9). My telephone doesn’t work at all. • Make sure the power cord is securely plugged in.
Appendix Troubleshooting • If the previous suggestions do not work, disconnect the telephone base from the telephone jack and connect the jack to 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 line cord might be defective. Try installing a new line cord. I cannot dial out. • Try all the suggestions above. • Make sure you have a dial tone before dialing.
Appendix Troubleshooting Out of range OR No pwr at base appears on my cordless handset. • Ensure you plug the telephone base in properly and the power is on. • Place the cordless handset in the telephone base for one minute to allow the cordless handset and base to synchronize. • Move the cordless handset closer to the telephone base. You might have moved out of range. • Reset the telephone base. Unplug the electrical power. Wait for 15 seconds then plug it back in.
Appendix Troubleshooting I get noise, static, or weak signals even when I’m near the telephone 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 as a result of DSL interference. Please contact your DSL service provider for more information about DSL filters.
Appendix Troubleshooting My cordless handset does not ring when I receive a call. • Make sure that the ringer is not off. Refer to Ringer volume in the user’s manual provided with your CL82311 telephone. • Make sure you plug the telephone line cord securely into the telephone base and telephone jack. Make sure you plug in the power cord securely. • The cordless handset may be too far from the telephone base. • Charge the battery in the cordless handset for at least 10 hours.
Appendix Troubleshooting My calls cut in and out while I’m using my cordless handset. • Other electronic products such as HAM radios and other DECT phones can cause interference with your cordless phone. Try installing your phone as far away as possible from these types of electronic devices. • Do not install this phone near a microwave oven or on the same electrical outlet. You might experience decreased performance while the microwave oven is operating.
Appendix Troubleshooting System does not receive caller ID when on a call. • Make sure you subscribe to caller ID with call waiting features from your telephone service provider. Caller ID features work only if both you and the caller are in areas offering caller ID service, and if both telephone service providers use compatible equipment. I subscribe to a nontraditional telephone service that uses my computer to establish connections, and my telephone doesn’t work. • Make sure your computer is powered on.
Appendix Troubleshooting The charge light is off. • Make sure you plug the power and line cords in correctly and securely. • Unplug the electrical power. Wait for 15 seconds, then plug it back in. Allow up to one minute for the cordless handset and telephone base to reset. • Clean the cordless handset, charger and telephone base charging contacts each month with a pencil eraser or cloth. • The battery may not be connected to the handset or is missing completely.
Appendix Maintenance Taking care of your telephone • Your cordless telephone contains sophisticated electronic parts, so you must treat it with care. • Avoid rough treatment. • Place the handset down gently. • Save the original packing materials to protect your telephone if you ever need to ship it.
