Seeking KT-79 transponder install/operational info

Hey all. I recently inquired about replacing my dead transponder (KT-76) with a worn out cavity. I've since bought an e-bay
special KT-79. I haven't installed it yet, but have powered it up on the bench. Things seem OK, except that the VFR button sends the
unit to code "4263" rather than "1200." Aside from the obvious "It's broke" response, is there any sort of programmability to this? I've
also got a KT-197 COM that has obscurely available "memories" obtainable via turn, push, twist, stand-on-your-head, twist-twist
combination. Anyone know if the KT-79 has has something similar to set what "VFR" means, or am I just hosed? I do not know if the code
corresponds to what's transmitted yet.

Just grasping as straws here...

Thanks,
-Cory
