When the KPA100 is installed, the KAT2 is removed from the K2 case, so this 
is not a problem, since it is not available.

If the KPA100 is installed remotely, AND the KAT2 remains installed within 
the K2 case, the KAT2 is DISABLED and cannot by use while the KPA100 is 
ATTACHED to the K2. In this case you will have to either use the KAT2-100 
(or whatever nomenclature it will bear), or another external ATU.

If you wish to tune up under low power (e.g. with the KPA100 OUT of the 
line), merely turn the power back to a level less than 11W and the KPA100 
will drop out of the line. Also, when the KPA100 is IN-LINE, with you press 
[TUNE] the output power from the KPA100 is set to 20W for ATU tuning purposes.

Hope this helps,
