How to use

Attach the headset so the microphone capsule sits near the corner of the mouth for optimal pickup. Power on the transmitter and the corresponding UHF receiver, ensure both operate on the same frequency or channel, and connect the receiver output to your PA or amplifier using the appropriate audio cable. Adjust gain on the receiver or mixer to achieve a clear, undistorted voice level.

Recommendations

For best results, test the system and check for interference before use, keep the transmitter battery charged or replaced, and position the microphone close to the mouth while avoiding direct breath into the capsule. Use compatible UHF receivers and maintain line-of-sight where possible to improve signal stability.
