5.2 Power Up
When powering up, all the Leds will flash once and then extinguish and then in turn sequentially illuminate 1
led at a time until all Leds are illuminated – the sequence takes about 14 secs during the boot cycle.
When the boot cycle is complete the RA24 will indicate the current state.
