DME FQS SWITCH SETTINGS


DME FQS SWITCH ADJUSTMENT



Arrow indicates the DME FQS adjustment switch in the computer. It's not required to open the computer to change the settings, but we wanted to show you what exactly your adjusting.



The DME FQS Switch Adjustment is located in the DME computer box. The FQS switch has a triangular female socket in the end for a special tool. We use a 2.5mm Allen wrench to adjust the switch. It's a snug fit and you should insert it with care.

When you rotate the switch all the way counter-clockwise until it stops, that's considered position 0. From there, the first click clock-wise from there is position 1, next click is position 2 and so on.
