How to use

Install the required batteries into the handheld microphone and switch the unit on. Ensure the corresponding UHF receiver is set to the matching 531.9 MHz frequency and that the receiver is connected to a sound system or mixer. Position the receiver to maintain clear line-of-sight where possible and set input gain on the mixer or amplifier to achieve the desired vocal level without clipping. Hold the microphone a suitable distance from the mouth (typically 5–15 cm) and speak at consistent volume for reliable transmission. After use, switch the microphone off to preserve battery life.

Recommendations

For optimal performance, use fresh batteries and check the receiver input levels before starting. Minimize interference by placing the UHF receiver away from large metal objects and other wireless devices. If possible, perform a soundcheck at the venue to confirm coverage and to adjust gain and equalization for clear vocal reproduction.
