Please note that there are 2 types of PCB that may be fitted to the single PCB version of this appliance.
The original style is coloured white and the newer version is green.
They are fully interchangeable, but the position and orientation of some connectors have changed.
This XSol model will show the green PCB in tests, if you are testing on a white PCB the test will remain the same.
The important differences between the two PCB's are highlighted below.
