aFlash Code Descriptions:

-Flash Fast: rapid blinking

-Heartbeat: Constant ½ second bright, ½ second dim cycles.

-A single flash code number signifies that the LED flashes X times at 2Hz, remains off for two seconds, and then repeats the sequence.

-X + Y flash codes signify that the LED flashes X times at 2Hz, remains off for two seconds, flashes Y times at 2 Hz, remains off for three seconds, and then repeats the sequence.
