My unit turns on ok, the after a short time (random frequency), the unit turns off. Thought it was a battery issue, but battery still shows sufficient power. Can only be turned on by side on button, no other way - so not in 'sleep' mode. It also turns off when I am midway through touching modes on the screen. Should I reset and see if that solves the problem? Or is it a catastrophic unit problem?
Thanks,
Matt
