Press and hold the multi-function rocker button on the receiver to enter the menu interface to check the status of channels (Channels in green are interference-free channels, while channels in red are channels that have interference.)

Push the rocker-styled button on the receiver up or down to select an interference-free channel and then press the button to confirm the channel.

Place the receiver at least 1.7 meters above the ground.

Ensure that the power supply is stable.
