Change frequency band of XTend radios

Is there any way to change the frequency band of XTend 900 Radios?

I have the XT09-SI radio, that is supposed to be used in North America with ISM 902MHz to 928MHz. Is there any way to change it to the International frequency band, ISM 915MHz to 928MHz?

Can I upgrade its firmware to one for XT09-SI-NA? Does it works?


What country do you want to use it in? I asked as there may be a way but it is dependent upon several things including where you want to use it.

I want to use it in Brazil.

Tiago, you need to purchase a new 9xtend radio from Vika Controls in Brazil. Otherwise you will not be legal.
