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.
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.
