Mk 107

I have a mk107 kit that I want to run on an external switched 12v supply, the problem is I need the kit to start operating as soon as the supply is switched on without having to start the sequence with the start button on the board; is the a mod I can do to by pass this on fuction without affecting the sequence change function of the switch

Sorry, this is not possible with this kit.
