Thought this would be a nice place to add up some lavatube features - Please let me know if i forget anything and i'll add it up..
- Press power button 7 times to get remaining voltage of battery
- Press and hold power to turn device off (same to turn back on)
- Press and hold + & - buttons for 5 seconds to lock voltage (same to unlock)
- Same voltage when changing battery - lock voltage as above let screen go off change battery as quick as you are able
- Voltage under load - press power 7 times - press and hold fire button and press power button one more time
I think that's pretty much it without going into the pure basics
