[Elecraft] KAT100 Problem

[Wolfgang, Larry, WR1B]

While trying to make a few contacts in the PA QSO party, I hit the Tune button to adjust the match to my antenna. All of the LEDs on the KAT100 light up and the relays cycle for about 5 seconds or so. Then will all of the LEDs still lit and the display showing 9.9:1, the radio switches back to receive. The same thing happens with all of my antennas, on all bands. I'll have to run without the tuner for now, but I'm looking for suggestions on what to look for. Anyone else have similar experiences?
 
Actually, the tuner has done this a few times, but usually works okay when I hit the Tune button again.
