Starting with UI Version 3.1.2 it is possible to export the backup files that are stored internally to the 4000 Series via the front mounted USB Port.
To export the backup files, first prepare a USB drive as detailed here : 4000 : Formatting a Memory Stick to FAT32 Format (4000 Series)
Insert the USB drive into the front mounted USB port and wait for the USB stick to be detected (approximately 5 seconds)
Press the 'Main Menu' key and navigate to 'Export Calibration Backup Files to USB'
An on screen dialog will appear, indicating progress of the copying process. Once all backup files have been copied the menu screen will disappear.
The backup files can then be accessed using your computer, and can be provided to Transmille for analysis as required.
