DFR1093-915 Brazil Frequency AU915

I am trying to configure the DFR1093-915 to operate on the Brazilian frequency band (915–928 MHz), which is similar to AU915-928.

When I set the region to Brazil, the system automatically defaults to US915, which uses a different frequency band. To work around this, I changed the country setting to Australia and attempted to adjust the band settings, but no options were available to select. When I refresh the page, options appear, but they display US915 frequencies instead.

Could you please assist me in setting the band to AU915 FSB2?

Best regards,

Julio
