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.

•Your cordless 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. Check the Adding and registering handsets section of your telephone user’s manual for the maximum number of handsets allowed. If the maximum number of handsets are already registered, you need to follow the deregistration instructions in the telephone user’s manual, then register the handsets and/or headsets you wish to use again, one at a time.

For registration to a headset base:

•You can register a maximum of two headsets to the headset base. If you already have two headsets registered to the headset base, you must deregister all the headset(s) before you register a different headset.

•If you registered the accessory cordless headset to a headset base, see the user’s manual for your headset base model TL7610/TL7611/TL7612 for additional troubleshooting. Visit
