Registering the handset
Before using your new handset, you must register it with
the base. During registration, you must enter the 15-digit
ID number of the telephone base. To find this number, go
to the base, press MENU, scroll down to select DISPLAY
BASE ID, then press OK.
The handset provided with your telephone is automatically
registered as Handset 1. Additional handsets will be
assigned numbers in the order they are registered (2, 3, 4,
etc.) up to a maximum of eight.
