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?
