NOTE
The Left and Right LEDs turn on after the center LED. This allows you to distinguish easily between the Center LED
and the Left/Right LEDs.
NOTE
If the Center LED begins blinking RED, it indicates that the Altitude AP's state has failed.
NOTE
Random delays do not occur during normal reboot. A random delay only occurs after vulnerable period power-down.
