It's dos software. I sometimes can and sometimes can't work with it but I do 
have the software edited for that radio to put the radio in the ham band. If 
you want it let me know and I can send it to you off list. As it happens the 
900 MHz hand held I use the most of all my collection is an MTX9250 so I 
know the radio very well and I'd buy more of them if I only had the money. I 
actually have 2 of them though I can't find one right now, my wife used it 
so it could be anywhere in the house. Seriously though, that is a good radio 
for the band, in fact if you want, talk to me off list, I may well be able 
to help you with programming to some point if you need it. I have all 900 
MHz repeaters in at least New England if not the whole country in my radio 
setup by zone so I stay on the zone for my part of the country or the 2 
areas I go in, eastern MA and north Shore MA  and it works out alright for 
me.
