Note: In the same a rea when mu ltip le data transceivers are commun icating 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 lowe r the transmit power, the c loser the transmission distance, but the working current won’t be declined in
exact proportion, it is recommended to use the maximu m 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.

Note: It is recommended to retain more than 50% o f the current marg in when selecting t he power supply, which will
help the data transceiver to work steadily for a long time.
