How to set them up when multiple sets of MARS 300 PRO are used at the same location ?

• Suggest using up to 3 sets of MARS 300 PRO at the same location
  
  
• Choose different frequency channels.
  Suggest using the Channel Scan feature on the Receiver to check the actual interference and then choose the Transmitter's clean channel.
  Do not use the same or adjacent channels；（eg A RX is channel 1, B RX should be ≥ channel 3）
  

                                   

• Distance between each Rx should be at least 0.5m
• Place all RXs 1.7m high
