WARNING: MESA Software Updates must be performed with the MESA unit connected to the AC Power Supply and with the battery sufficiently charged. Without sufficient power there is a small risk of the MESA losing power during the update and rendering the unit inoperable.

Updating the software on your MESA unit:
1. Copy the downloaded .bin file onto the root drive of a USB thumb drive (FAT32 partition).
2. Insert the USB thumb drive into the MESA.
3. After the MESA has a chance to read the drive, the software update screen is displayed.  This screen will indicate the version number found.  Please confirm that it is the expected version.
4. Select "YES" and the MESA will begin the software update. The software update can take upwards of 10-15 minutes.  A progress bar is active during the update. DO NOT REMOVE THE USB THUMB DRIVE DURING THIS PROCESS.
5. At the end of the software update, the MESA will restart.
