The MX2 saves all settings with the exception of the motor speed, for this reason it's good to know how to reset the system in case your getting unexpected results and need to start fresh.
To reset the MX2:
-Navigate to Settings>Reset Mem> and turn it ON (don't forget to tap the [enter] button after setting to accept)
-Pull the power and replace the power ('hard reboot' the controller)
Your MX2 will clear the memory and revert to factory defaults.
