Steve,
Those LEDs are activated by 2 pins on the MCU, but the actual activation
of ATTN and RIT/XIT is done via the AUXBUS signalling.
Unless you know that they worked shortly before you bought it, I would
suggest that it may have been unused for some time.
On the chance that the problem is caused by oxidation on the pins of the
MCU/socket, I suggest that you remove and reseat the MCU IC. It is on
the Front Panel board, and is the only socketed IC in the K1.

I recently purchased a K1 and found that the LED's for the RIT and ATTN don't
function correctly. When I turn on the rig the LED's cycle correctly then go
out. When I push either of the buttons and turn the RIT or ATTN on, neither of
the lights come on.
