Note
】
Use multiple groups of digital radio stations to communicate one-to-one at the same time in the same area. It is
recommended that each group of digital radio stations set the channel interval to be more than 2MHz;
The lower the transmit power, the closer the transmission distance, but the working current will not decrease
proportionally. It is recommended to use the maximum transmit power;
The power adjustment function cannot accurately feedback the actual transmit power of "medium", "low" and
"extremely low". The values in the table are for reference only, and other powers can be customized;
