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 re-regis-
ter all handsets again.
To de-register all handsets
• Press and hold
HANDSET LOCATOR /INTERCOM on the main telephone base
until the IN USE light starts to turn on and flash (about 10 seconds), then
release the HANDSET LOCATOR /INTERCOM button.
• Press and release HANDSET LOCATOR /INTERCOM 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 44.
