The Radio Information Board

I just picked up a UHF VX-P929 with the VHF sub band receive board. I can use the fpp to program the uhf frequencies, but the vhf just look like uhf frequencies. I've tried to change the vhf freqs, but it doesn't work. Has anyone figured out how to program the sub board from the front panel?

In one of the drop down menu's, you need to tell it that it has the sub receive board.

I can program it via the software, but not through the fpp.
