MX3Plus OS Upgrade
Introduction
Depending on the size of the operating system, the total time required for a successful upgrade may require several minutes.
The OS upgrade files are unique to your MX3Plus physical configuration and date of manufacture. OS upgrade files designed
for one device configuration should not be used on a different device configuration.
Preparation
l Please Contact Technical Assistance to get the OS upgrade files.
l Use ActiveSync to back up MX3Plus user files and store them elsewhere before beginning an upgrade on the MX3Plus.
l Maintain an uninterrupted AC/DC power source to the MX3Plus throughout this process.
l The SD / CF card with the OS and systems files must be present for the MX3Plus to boot. Removing and installing SD
or CF cards should be performed on a clean, well-lit surface.
l Always perform OS updates when the MX3Plus has a dependable external power source connected to the MX3Plus
and/or a fully charged main battery.
Procedure
1. Verify a dependable power source is applied to the MX3Plus and will stay connected during the upgrade procedure.
2. Establish an ActiveSync connection between the MX3Plus and a desktop/laptop computer.
3. Download the OS files from the desktop/laptop to the MX3Plus's System folder.
4. During the file copy process to the MX3Plus System folder, when asked “Overwrite ?”, select Yes to All.
5. Review the files that were downloaded to the System folder.
6. Restart the MX3Plus.
7. Disconnect from ActiveSync.
8. When the OS finishes loading, check the OS update version by selecting Start > Settings > Control Panel > About >
Software tab.
The touch screen may require calibration, however most Windows OS versions save the calibration data, eliminating the need
to calibrate.
Battery State and OS Upgrade
Honeywell recommends a fully charged main battery be cabled to the MX3Plus prior to reflashing or 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 MX3Plus will be left in an
inoperable state.
When main battery power level is too low, connect external power to the MX3Plus before performing the upgrade procedure.
Do not disconnect external power before the upgrade process is complete.
