[Elecraft] KX3 Question

[Phil Hystad]

Gang, I just finished putting together my KX3 with the filter option, ATU, and battery charger.  I am just about to do the calibration for the filter but I noticed that there is an LED or something that flashes, maybe once per 2 seconds?, inside the KX3.  I can see it through the key/paddle plug opening.

Does anyone know what this is?  Is there meaning to the flash?  Is it important?

Thanks,
