The PCB has a number of configuration ‘jumpers’ on it where the default position is made by
tracks connecting 2 vias (a ‘via’ is a small plated hole in the board that connects top side
tracks to bottom side tracks).
Three of these jumpers have to be cut from their default position and left ‘open’. These are
