How to use

Attach the Omnitronic BHD-02 to your belt or waistband using the integrated clip, connect a compatible wired headset or lapel microphone to the microphone input, and set the volume control to a low level before speaking. Gradually increase the volume until speech is clear and comfortable for the audience; avoid maximum volume settings to reduce distortion. For classroom or tour use, position the microphone element close to the mouth but outside the direct airflow to reduce breath noise. Turn the unit off when not in use to conserve battery power.

Recommendations

Use the belt amplifier in environments with up to small group sizes and short listening distances. Prefer a low to medium volume setting for intelligible speech and reduced background noise amplification. Use a compatible low-profile headset or lapel microphone for hands-free clarity, and store the unit in a dry place when not in use.
