Usually with *most* programmable /\/\ radios you can't tell. The only way to approx. the bandsplit would be to read the serial number. (And even then with out a proper model breakdown you wouldn't be able to find out...RSS would be the only way at that point.)
But I would assume if the radio is VHF its between 132 - 174 mhz. UHF it could be 403 - 512mhz.
... err, wow I should have read skip's post more thorughly, he said basically the same thing ...
