Deregister handets
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.
If you want to register a handset to another compatible base (

individually to the desired telephone base.
To make deregistration easier, read all of the instructions below before you begin.

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
