4 If present, remove the KXB30 module. Remove the KXB30 wires from the KX1 main PCB and clear the pads on the KX1 main PCB of all solder. Replace C2

5 Turn the KX1 PCB over and cut the trace from CB to C27/R1 as shown in Figure 2. Use a sharp hobby knife and cut across the trace several times as n

6 Rotate potentiometer R1 fully clockwise and check the resistance between ground and the part of the cut trace that goes to the open solder pad for C
