System Boot Internal Light Indicators – There is one red and one green LED light inside the MagArrow’s
battery compartment. These two lights will flash in a specific sequence when the power button is
pressed and the system is booting properly.
As soon as the power button is pressed, a red light, which sits between the Power Button and the USB,
will come on solid for about 3 seconds. Then a green light, located near the USB, will slowly flash and
hold for about 1-2 seconds and then turn off. Then the red light will begin to flash at 10Hz (10 samples
per second).
If the red light does not flash, but remains solid instead, that means the system did not boot correctly
and the power should be cycled again. Cycle the power by pressing the power button once.
