To Adjust the Mouthpiece

  1. Hold the receiver securely against your ear with one hand. With your other hand, adjust the clickstop turret and the microphone so that the tip sits two finger- widths from the corner of your mouth. To prevent breath noise, avoid putting the microphone in front of your mouth (see figure 3.1 above).
  2. Carefully bend and shape the boom with both hands as shown in figure 3.2, above. Avoid bending or twisting the boom near the microphone or earpiece.
