Operating Instructions

Wearing the Transmitter

Attach the transmitter to your clothing using the belt clip. Position the built-in microphone approximately 6-8 inches (15-20 cm) from your mouth for optimal audio capture. For best results, use the included fur windshield to reduce wind noise when recording outdoors.

Adjusting Gain (Volume)

Use the '+' and '-' gain control buttons on the side of the transmitter to adjust the microphone's input level. Monitor your audio levels on your recording device to prevent clipping or distortion.

Mute Function

Briefly press the Power/Mute/Pair button on the transmitter to mute or unmute the microphone. The status indicator will change to reflect the mute status (e.g., blinking slowly or changing color, refer to the status indicator guide for details).

Troubleshooting

Problem	Possible Cause	Solution
No sound or low volume	Transmitter not powered on. Transmitter and receiver not paired. Microphone muted. Gain level too low. Receiver not fully inserted into iOS device. iOS device volume too low.	Ensure transmitters are powered on (solid blue indicator). Re-pair the transmitters and receiver as per "Setup and Pairing" section. Unmute the microphone by pressing the Power/Mute/Pair button. Increase the gain level using the '+' button on the transmitter. Ensure the RXDi receiver is securely connected to the Lightning port. Increase the volume on your iPhone/iPad.
Interference or static noise	Obstacles between transmitter and receiver. Proximity to other 2.4GHz devices. Environmental electromagnetic interference.	Reduce distance and clear line of sight between devices. Move away from Wi-Fi routers, cordless phones, or other 2.4GHz devices. Activate the noise cancellation feature on the transmitter.
Transmitter not charging	Faulty USB-C cable or power adapter. Charging port obstruction.	Try a different USB-C cable and power adapter. Check the USB-C port for debris and clean gently if necessary.
