Dick,

First make certain the ATU menu parameter is set to "tun".
Then hold both the buttons in the upper right of the front panel 
together to initiate a TUNE.

If the KAT1 already has a tuning solution in place, the process will go 
quickly and you may have to listen closely to hear relays click.
When it has found a tuning solution, it will display the resulting SWR.  
Tap any button to exit the TUNE process.

Once you have Tuned the KAT1 to a particular antenna on a band, when you 
return to that band it will switch to that tuning solution.  So if you 
have done a TUNE on all bands, there is no need to re-tune unless you 
change antennas.

73,
