1. RX scan channel and choose a clean channel to avoid interference, then place the TX and RX 0.5m away and pair TX and RX again simultaneously.
2. Please use the device within the line of sight. If there is a wall blocking the signal, the signal will be attenuated, causing the screen to freeze or disconnect.
When there is crowd blocking between the TX and RX, the RX should be elevated 1.7m to avoid signal attenuation.
