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 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.
NOTES:
1. 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 charger.
2. You can only deregister 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 41.
