AT&T E5937 Replacing a handset

44

Appendix

If you are replacing a handset on a system that has the maximum number of registered

handsets (four) or wish to change the assigned handset number of your registered

handsets, you must first de-register the handsets, then de-registration all handsets.

To de-register all handsets

• Press and hold HANDSET LOCATOR on the main telephone base until the IN USE

light starts to turn on then flash (about 10 seconds), then release the HANDSET

LOCATOR button.

• Press and release HANDSET LOCATOR again. The IN USE light will turn off and in

a few seconds, all handsets will be de-registered.

• All handsets will show NOT REGISTERED if de-registration was successful.

NOTES:

1. If the de-registration process was not successful, you may need to reset the system and try again. To reset: pick up

the handset and press the PHONE/FLASH button, then press the OFF/CLEAR button and place the handset

back into the cradle.

2. You can only de-register handsets when the handsets and the base are not being used.

3. To re-register the handset to the telephone base, follow the registration instructions on page 43.
