WEARING THE HEADSET FIGURE 2 ADJUSTING THE HEADSET • If the headset feels loose or uncomfortable, carefully bend the sides of the wireframe to make it tighter or looser (Figure 4A). The angle of the wireframe earpieces may also need adjustment (Figure 4B).
OPERATION Connect the WH20 to the microphone input of a wireless microphone transmitter or a bal- anced wired microphone input. NOTE: The WH20 is a dynamic microphone and has inherently lower output than condenser microphones.
Slide the headband around the wireframe to its original position. Reattach the cable with the plastic retainer. Note that the elastic headband supplied with the WH20 is not a standard size; head- bands purchased in stores are too long for this application.
