VRP Remote Upgrade Procedure
There are two stages that will be displayed for the majority of the time. The first is while the WC
is transferring files to the FMC, it will display a “6” and the Communication Icon will blink. This stage
will last approximately 7-8 minutes.
When the FMC is sending a file to the MCS, the digits “5L” will be displayed. This stage will last
approximately 11-12 minutes:
This will persist until near the end of the Remote Upgrade process as the WC is waiting to hear
if the MCS and/or FMC upgrade process was successful. After this stage a “9” will be displayed for
approximately 1-2 minutes:
After the remote upgrade has been completed, the WC screen may restart or go blank. Remove
the SD Card to restart the WC:
