+## How to extend SubGHz supported frequency range
+
+#### CC1101 Frequency range specs: 300-348 MHz, 386-464 MHz, and 778-928 MHz 
+#### This setting will extend to: 281-361 MHz, 378-481 MHz, and 749-962 MHz
+
+1. Please do not do that unless you know what exactly you are doing
+2. You don't need extended range for almost all use cases
+3. Extending frequency range and transmitting on frequencies that outside of hardware specs can damage your hardware!
+4. Flipper Devices team and/or unleashed/RogueMaster fw developers are not responsible of any damage that can be caused by using CFW or extending frequency ranges!!!
+
+If you really sure you need that change, find `subghz/assets/extend_range.txt` file on your microSD, read comments on first lines
+and change `false` to `true`
