When the cordless system is operational, LED1 must be on (green) indicating
power on. The other LEDs must be off.
When LED2 is on (red), the cordless system has sent a message that has not
yet been read with CSM. The system may still function properly when LED2
is on.
LED3 - LED6 indicate fault situations when on (red).
