★ Note: In the same area when multiple data transceivers are communicating one to one at the same time, it is
recommended to set the channel spacing between each group of data transceivers at 2MHz or more.

★ Note: The lower the transmit power, the closer the transmission distance, but the working current won’t be declined in
exact proportion ,it is recommended to use the maximum transmit power.

★ Note: The higher the air data rate, the faster the transmission rate, the transmission distance is also closer; when the
rate meets the requirements, the lower air data rate, the better quality.
