Fault Light on Neural Loudness Control

We have a Neural loudness control + Multimerge (does a great job BTW.) that occasionally gets a fault light that lights up.  It is still working fine and we can find no evidence of a malfunction. Just the fault light.  The issue is how do you reset the fault light?

Go to the home screen by pressing back until you get to a screen that says "Menu" and "About".  Then go to About.  Look for Reset fault light and there you go.  Why is it in the About section?
