The CDP (and DVI) will be shipped with the most current version of firmware. Periodically, SKYTRAC Systems
will supply a new version of firmware that will add functionality to the CDP. These files will be available on the
SKYTRAC website (www.skytrac.ca) to download and install. See the DVI user guide (DOC0499) for updating
firmware on the DVI-300.
