Before using a 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.

Follow the instructions provided with your new handset to register it for use with your telephone.

The handsets provided with your telephone are automati- cally registered as Handsets 1 and 2. Additional handsets will be assigned numbers in the order they are registered (3, 4, etc.) up to a maximum of eight handsets.
