Reset SG-3100 to factory defaults

[Phil A]

I have lost all access to my SG-3100. Definitely operator error. I was changing my LAN IP address and the screen went red and I haven't been able to get back into it since. I tried the reset button but I cannot even get to the log in screen.
Can someone help a rookie out and tell me how to get back to start?

Connect to the serial console and use menu option 4.
