NOTE:
The diagnostic pattern will consist of a two digit number being represented by a first group of LED blinks (1 through
9) in amber, followed by a 1.5 second pause with the LED off, and then a second group of LED blinks (1 through 9) in white.
This is then followed by a three second pause, with the LED off, before repeating over again. Each LED blink takes 0.5
seconds.
