Tips and tricks

In order to obtain the best receiving

Transmitter effective signal range depending on the working environment and conditions.May is between 10 m and 100 m.

Transmitting and receiving antenna should not be obstacles blocking the line of sight.

When the poor reception conditions should in receiver through the antenna cable connecting two separated antenna.

Transmitting and receiving antennas should keep 5 m minimum distance.This can avoid receiver of radio signal overshoot.- between receiving antenna and steel or concrete wall should ensure the minimum spacing of 50 cm and with V shaped antenna calibration.

In the multi channel device operation

When using multiple transmitters,should avoid the transmitter spacing is too short to form a transm ission line interference.The transmitters to maintain at least 20 cm spacing.
