Reset to Factory Default

Press and hold the function button (FN) continuously for at least 5 seconds to load the factory default
configuration. After the factory default configuration has been loaded, the system will reboot automatically.
The Power LED will blink on and off for the first 5 seconds, and then maintain a steady glow once the system
has rebooted.
We recommend that you only use this function if the software is not working properly and you want to load
factory default settings. The Reset to Default functionality is not designed to hard reboot the UC-8112-ME-T.
ATTENTION
Reset to Default will erase all the data stored on the boot storage
Please back up your files before resetting the system to the factory default configuration. All the data stored
in the UC-8112-ME-T's boot storage will be erased when it is reset to the factory default configuration.

Real-Time Clock

The UC-8112-ME-T's real-time clock is powered by a lithium battery. We strongly recommend that you do not
replace the lithium battery without help from a qualified Moxa support engineer. If you need to change the
battery, contact the Moxa RMA service team.
