About Handset Registration

You must register this (and any other) handset with the base, following the directions in “REGISTER THE HANDSET.” This handset is compatible with telephone models 5840 and 5830.

The original handset that came with the base is automatically registered as Handset 1.

Additional handsets will be assigned Handset 2, Handset 3, Handset 4, Handset 5, and Handset 6.

Whenever you install a handset battery pack, the handset will display SEARCHING FOR BASE (if it’s registered) or ENTER BASE ID (if it’s not registered).
