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.

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.
