Multiple Sets Installation

Suggest using up to 3 sets of MARS systems at the same time.

• Choose a different channel, and the channel interval should bigger than 2,
• please use the channel scan function on the RX to check the status of channels, then select a clean channel on the TX.
• Place each RX at least 0.5m away from the other.
  

So when you say 3 sets, is it TX + 2 x receivers?
I am trying to connect 2x M1 monitors and 1x RX at the same time but it does not work
