spectra F7 Mode Opt 1 troubles

[jjjjjjjjjjjjjjj]

I have a uhf spectra when i put in certain frequencies in the 476 477 mhz range.
The F7 Mode Opt 1 won't allow the high power setting.
Is their a way around this

I have done some more playing and still can't get this working the radio is a 450 to 482 mhz high power spectra model no. ta9gx+079w
i.d no. t84gxa7ha9ak
I have tried different rss versions and even a different codeplug .
I am guessing it is a limitation in the spectra1.exe in the rss as soon as i put in 470mhz or above it locks out high power.
If i turn the power up in the low power setting adjustment i can get more power just not sure if this is safe at all.
