Updating the Operating System
Introduction
All 2-Series control systems have an operating system file with a .cuz extension.

download from the Crestron website.
To download an update, click the appropriate zip file, choose the Save to Disk
option, and then specify the directory where the update is stored.

may be required to register to obtain access to certain areas of the site (including the
