Any help advise appreciated,
I have a relatively new MRT PTX that has stopped working, it has the blue light on when powered up but during heats at my club it stopped working

I have been using this PT for a few months with no issues.
I have tried an alterative PT in the car and that works so rules out all other factors apart from the MRT PTX
Can they be reset or would it have to be sent back to the manufacturers ?
Cheers
Stu
