 - The zipped system software file from our site and Winzip or similar unzipping software installed on your PC
 
To load the system software onto the CompactFlash card:
- Connect the CompactFlash Card Reader to an available USB port on your PC and plug the CompactFlash card into the reader.
 - Download the system software zip file from our site to your desktop.
 - If you are familiar with WinZip, you can extract the file directly to the CompactFlash card and skip steps 3 and 4.
 - Double-click the file you downloaded in step 1 to have WinZip extract it.
 - WinZip will extract the files to a folder on your desktop
 - Copy all the unzipped files (not the folder) to the root directory of the CompactFlash Card.
