1. Place the card with the new image files on it into the SD slot. The label on the SD card should be facing up.
2. Close the hatch. When the hatch is being closed, carefully move cables and wires back into the cavity before securing
the hatch. Before securing the hatch completely, examine the seam between the front and back half of the MX9. If the
gasket is off-center, loosen the screws a little, adjust the gasket and re-tighten the screws.
3. Press the Power button to turn the MX9 on.
4. The update run file in My Device > Storage Card automatically launches.
5. Important: If a failure occurs during the update, DO NOT RESTART (or coldboot). Follow the instructions on the screen
to Exit the update utility then restart the update utility.
6. Do not touch the device until the install/update is complete.
7. When the process is finished, remove the SD card following the instructions in Accessing the SD Card Slot.
8. When finished, press the Power button.
Check the OS update version by viewing the About or About Info (or About LXE) panels.
Note: If the application displays “Update OS Image Failed” or “Update Boot Loader Image Failed”, do not Restart the system
manually. Perform a warm boot, then try the upgrade again. Restarting will cause a system crash, since there is no
valid image in the MX9 system.

Contact Technical Assistance (page 15-1) if the device won't boot up after the upgrade is finished for re-imaging
options.
Warning: Opening the device e.g., removing endcaps or access panels, etc. could void the user's authority to operate
this equipment.
Battery State and OS Upgrade
A fully charged main battery must be installed in the MX9 prior to upgrading the operating system. A prompt may appear
when the battery reaches Critical Low that informs the user there is not enough power in the main battery to perform the
upgrade.
The operating system will not be able to execute the OS update when the battery level is too low (25% or less), as there is
a high risk that the power remaining in the battery expires when executing the upgrade and the MX9 will be left in an inop-
erable state.
When main battery power level is too low, connect external power to the MX9 before performing the upgrade procedure. Do
not disconnect external power before the process is complete.
