How to use

Charge all units using the supplied USB‑C cables before first use. Power on the receiver and transmitters; they will automatically pair. Select Video mode for direct camera or recorder connection or Bluetooth mode for pairing with mobile devices. Connect the receiver to your camera, smartphone or mixer using the appropriate TRS/TRRS cable. Use the monitoring headphones to check input and adjust microphone placement to ensure clear capture of the speaker's voice. After use, power off devices and store them in the supplied bag.

Usage recommendations

For best results place the lavalier microphone on the speaker’s chest, 15–25 cm below the chin, and use the wind shields outdoors. Maintain a clear line of sight within the stated 10 m range and avoid placing the receiver and transmitters too close to large metal objects or strong RF sources.
