= Installing Custom Applications =
This guide will explain how to install custom applications in the Cardinal 825 Digital Weight Indicator. 

== Requirements ==
 A USB flash drive or network connection is required. The application file should be copied to the USB flash or network share. For USB it is recommended to not have a great deal of other files on it as this may slow down or otherwise cause trouble with the scanning for files.

== Installing Your Custom Application ==
1. From the "Application Menu" select "File Manager". If the "File Manager" option is not present use the "Configuration" "Enable/Disable Menu" option to enable the file manager then go back to the application menu.

2. Updates can be performed from USB or a network share. Using a network will require that the 825 have a proper IP address and netmask setting and the network share must be reachable. The example will show using USB. Select "Choose an update file from USB Flash".

4. Select the button with the "Application: xxxxx" showing the file name of the desired application to install or update. The display will show "Are you sure you want to install/update Confirm: No". Press "Y" to select "Yes" and ENTER.

5. The file manager will check the USB flash drive to see if there is an accompanying signature file such as custapp.sgn to provide verification of the application developer. If the signature file is not found the file manager will prompt for the menu name to appear in the application menu.
