Select options
Depending on the application, different options may be selected.
Holding switch, SW1, down will show the current setting on the 4 LEDs. Holding this switch down for longer than 5 seconds
will cause the LEDs to cycle. Release the switch, SW1, when the correct pattern of LEDs is illuminated, and this choice will
be stored. Refer to the Control Logic section for further explanation.
