Recovery
In all cases where an error is detected, the Remote Upgrade process is terminated and must be
restarted for it to continue. To facilitate this, the system is automatically reset when the Key Card is
removed from the WC. Before doing this be sure to have noted the error displayed on the screen.
After removing the Key Card, wait a few seconds until the WC restarts and the screen goes
momentarily blank. Once the Smart Icon is displayed again, the system is ready for another Remote
Upgrade attempt.
If the screen never seems to reset, there may have been an issue relaying the reset command. In
this case it will be necessary to cycle system power for full recovery.
