Answer: the transmitter and receiver should be set up in a high position, 1.5-2 meters or more; the antennas should be fan-shaped and forward facing for the best transmission effect; the LNA mode should be set in L (low gain mode) when multiple transmitters work at the same time, please ensure that the distance between the transmitters is at least 1 meter or more; if there is still mosaic or cardon, please switch the channel to medium channel.

Answer: if the delay configuration has been changed, please confirm the software version of the codec board and contact the technician in time. If the software version is too low, you need to upgrade the software.

Answer: in two cases: 1. In a close distance, if both transmitters and receiver are connected with 4 antennas, the distance between the machines need to be extended to 5 meters and the LNA mode is set to “L” (low gain mode). When multiple transmitters are working at the same time, please ensure that the distance between the transmitters is at least 1 meter or more. 2. In a long distance, the transmitter and receiver are set up in a high position, 1.5-2 meters or more, and the LNA mode is set at “H” (high gain mode). The antennas are fan-shaped and front-facing for the best transmission. When multiple transmitters are operating at the same time, ensure that the transmitters are at least 1 meter apart.
