Notes on Pairing:

• Disabling noise cancellation on one TX transmitter applies the same setting to other TX devices.
• The RX receiver only displays the pairing status of the connected device. After resetting the RX receiver's pairing, the light will flash blue rapidly for 2 minutes. If pairing is not completed within 2 minutes, the blue light will flash slower, indicating the RX receiver is still waiting for pairing.
