GX440 Radio Card Swap MC7750 to MC8705

Hello all,

I am trying to change the MC7750 card to the MC8705 in a GX440 so I can get the carrier frequencies I need. I have the new MC8705 card installed in a GX440 but when I attempt to update the Radio Module Firmware the unit says it needs to be for the MC7750. How do I tell the unit that it has a different radio card installed?
