Replace a handset
If you want to replace a handset, or reassign the designated handset number of a registered handset, you must deregister all handsets that are registered to the telephone base. Then register each handset individually.
To make deregistration easier, read all of the instructions below before you begin.
To deregister all handsets:
1.Press and hold 
/FIND HANDSET on the telephone base for about 10 seconds until the IN USE light on the telephone base turns on and starts to flash.
2.Immediately press 
/FIND HANDSET again. You must press 
/FIND HANDSET while the IN USE light is still flashing. The IN USE light flashes for approximately five seconds.
3.All handsets display To register HS and See manual alternately when the deregistration process completes. The deregistration process takes about 10 seconds to complete.
To register the handset(s) to the telephone base again, follow the registration instructions on the previous page.
•You cannot deregister all handsets if any other system handset is in use.
•If deregistration fails, you may need to reset the system and try again. To reset, unplug the power from the telephone base and plug it back in.
•Even if the battery is depleted, you can still deregister all handsets by following the steps above. After the handset is charged for at least 10 minutes, the handset alternately shows To register HS and See manual.
