NOTE: Upgrading the firmware resets the Coordinate Matrix to the factory default settings (if the Retain Current Settings box is not checked). Prior to performing this procedure, backup the Coordinate Matrix settings (see Create Backup of Coordinate Matrix in the product manual).

This process can take as long as 50 minutes, depending on the connection speed on the CFA-24 network.

Telebyte recommends the use of Google Chrome browser (version-11.0.9600.17937 & update versions -11.0.22) for the most stability.
