How to use

Connect the VHF receiver to a mixer or powered speaker using the receiver’s audio outputs and supply power to the unit. Turn on the handheld transmitter and the receiver, then verify that the units are operating on the matched 212.35 MHz frequency. Adjust input gain on the receiver or connected mixer to set a clear level without clipping. Hold the handheld transmitter 5–15 cm from the mouth for consistent voice capture and avoid handling noise by maintaining a steady grip. If interference or dropouts occur, reposition the receiver or user to improve line-of-sight and reduce obstacles between transmitter and receiver.

Recommendations

For best results, ensure batteries in the handheld transmitter are fresh or fully charged before use, place the receiver away from large metal objects and other RF sources, and perform a soundcheck in the intended venue to set optimal gain and placement. Maintain a clear line-of-sight where possible and keep the handheld transmitter at a consistent distance from the mouth to preserve intelligibility and reduce handling noise.
