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 fast
er the transmission rate, the transmission distance is also closer; when the
rate meets the requirements, the lower air data r
ate, the better quality.

★ Note: It is re
commended to retain more than 50% of the current margin when selecting the power supply, which
will help the data tra
nsceiver to work steadily for a long time.
