How to reset a Mikohn Supreme controller back to factory defaults

(1/1)

knagl:
On the Supreme, I found that you can force it to clear its RAM by doing the following:

- Unplug the power
- Move the configuration slider switch to the "config" position (in the direction that the arrow on the board points to)
- Hold down BOTH of the buttons normally used in the config menus
- While holding both buttons, plug the power back in
- Release the buttons once you start seeing some signs of life/clearing RAM on the display.

If it works, you'll see a message that it's clearing the RAM.  On the Supreme it takes a while (3-5 minutes) to finish, while displaying various messages and even a failure message at one point.  Leave it plugged in and be patient.  It should eventually reboot and bring you to the config menu (since the switch is in the config position).  It should then be back to its factory defaults.
