When you press the MODE button on the left, does it cycle through 
AUTO/MAN/BYP?

If you leave it on AUTO or MAN and power-cycle the unit, does it power 
up in the same mode?

BTW, you should almost always use the KAT500 in the MAN mode because 
AUTO initiates a tuning sequence every time it detects RF.

First you should "train" the KAT by stepping through all the bands of 
interest at the Elecraft-recommended frequency intervals and giving it 
10-20 watts of RF, so it will remember the settings, and automatically 
energize the relays accordingly, so the antenna is tuned immediately for 
every QSY.

I train my KAT in the MAN mode, then tapping the TUNE button each time I 
transmit the 10-20 watts, but you can use the AUTO mode for training if 
you wish.
