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.

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.
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.
All handsets display

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
