Replacing a handset

If you are replacing a handset on a system that has the maximum number of registered handsets (4) or wish to change the assigned handset number of your registered hand- sets, you must first de-register the handsets, then re-register 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-register was successful.

NOT REGISTERED

NOTE: If the de-register process was not successful you may need to reset the system and try again. To reset: pick up the handset and press the PHONE button, then press the OFF button and place the handset back into

the cradle.

NOTE: You can only deregister handsets when the handsets and the base are not being used.

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