Using Lapel Wireless Microphones

    Proper Microphone Placement Proper Microphone Placement

  1. How to attach
    • If a microphone clip is not already attached, fit the clip to the groove in the head assembly. Clip the head assembly to a lapel, button area of a shirt, or necktie, preferably about two buttons down as shown in picture above. The clip can rotate 360� for attachment from any direction.

  2. Tips for convenient use
    • To avoid feedback, use the microphone with your mouth put as close to the microphone top as possible.
    • Some microphone head assemblies are equipped with a foam cover (windshield). Please do not remove this cover because it helps muffle undesired sounds.
    • Adjust the volume control to an appropriate volume level that prevents feedback. The system is prone to feedback if the microphone comes too close to the speaker.
    • Take care not to drop the unit on to a hard floor.
    • Do not flip or blow into the microphone head.
    • Never open the unit or touch its internal components.
