Please see the following blog post for specific modes which the V15 and V44 both feature. Including always on mode and auto off mode. Switching between auto on and auto off modes requires depressing the power button (and keeping it depressed) for approximately six seconds until all the status LED's blink repeatedly. It is possible to check the current mode when the unit is on by pressing the power button twice very quickly. If the unit turns off, then you are in auto power off mode. If the unit remains on, then you are in always on mode.
