I have a VT75D for some time now, but from the start it has a problem.
The 75C board resets itself spontaneously on an irregular basis.
When vaping it performs okay but sometimes after two vapes it resets and sometimes after 20 vapes.
I tried escribe several times to adjust settings, but doesn't help, I cleaned it which doesn't help also.
Eventually i opened up the modand made sure battery contacts are all good, still no solution, does anybody have an idea what to do?
