Registering the Handset
You must register the handset to the base before you can use it.
Only one handset can be registered at a time. (If an accessory
handset has ever been registered to a base, you must reset the
handset before you can register it to a new base.)
Note: The model number for your telephone base is located
on the bottom of main base unit.

base, place the accessory
handset in the base. While
