Sounds like a batch II camera, the power light on the batch I cameras is red and the record light blue.Somethings the red light will go solid and will not respond to input, need to 30 second power off
Somethings after pressing a button (cannot remember which) the screen will show a circular row of dots, unit becomes unresponsive, need to 30 second power off.
When I connected it to a portable USB charger, battery, size of lipstick, unit switched between making two tones and flashing through all three light, need to 30 second power off.
