| Hello, I just received my GMC-320 and it seems to be defective.
It is self resetting from time to time (irregular time intervals). I figure that, because it sets the CPM total count counter back to "0".
The display also goes off for the fraction of a second and it looks like it is restarting somehow (very quick).
I switched it on and the first time it self reset after about 5 minutes. The second time it self reset not even a minute after that. The 3rd time it self reset after about 12 hours.
So probably there is a loose contact within the unit.
1. Is it a known problem?
2. Should I return the unit and have it replaced?
