Getting started

Deregister handsets and headset

If you already have 10 registered handsets and need to replace a cordless
handset, add a cordless headset (AT&T model TL7600, sold separately); or,
if you wish to change the assigned extension numbers of your handsets,
you must first deregister all the handsets, and then re-register each handset
you wish to use. Please read carefully through all the instructions on this
page before beginning the deregistration process. Deregistering a cordless
handset does not remove the data saved on the handset.
This process deregisters all cordless handsets and any cordless headset
registered to the telephone base. Please make sure the telephone system is
not in use before deregistration.
1. On the telephone base, press MENU
2. Scroll down to Registration and press
3. Scroll down to Deregistration and press
4. The telephone base screen shows Deregister all
handsets? <=No >=Yes. Press REP to exit or press
SKIP to continue the deregistration.
5. The telephone base screen shows Deregistering. It takes
up to 10 seconds to complete the deregistration. The
screen shows All handsets deregistered and beeps when
the deregistration is successful.
NOTES:
1. If the deregistration process is not successful, you might need to reset the system and try again. To
reset: you can press EXIT on the telephone base. You can also reset the telephone base by unplug-
ging the power from the telephone base and plugging it back in.
