DATA AND CONFIGURATION LOSS
 Disable the EWF Manager before making any permanent changes to the
hardware, software, or Operating System of the Industrial Personal Computer.
Confirm that the EWF icon in the Windows system tray has a red “X”.
 Re-enable the EWF Manager after making permanent changes and confirm that
the EWF icon in the Windows system tray does not have a red “X”. This can help
extend the operating life of the CFast card.

Failure to follow these instructions can result in equipment damage.
