Batteries ran totally flat and unit wouldn't switch back on.
This one is mostly on me as I accidentally left the unit unplugged, but once the batteries were flat the unit wouldn't switch on even when plugged in until I swapped the batteries.
A few suggestions though:
- Can the CAD beep when it's unplugged / running low on battery?
- Could the app notify me the CAD is running low on battery?
- Could the app notify me when the CAD has been offline for sometime?
- Could the CAD shutdown sooner, to reserve enough battery to function when plugged in?
