2.Rotate the entire boom overhead to wear the microphone on either the right or left side of the head.
3.For best noise cancellation, position the microphone as close to the mouth as possible and speak in a normal voice (Figure 4).
4.To activate noise reduction, plug the headset into the battery or power module. To turn off noise reduction, unplug the headset from the battery or power module.
5.With the headband resting securely on the top of the head, check that the ear cups are centered over the ears. Reposition them if nec- essary by moving the headband sliders out or in. Proper performance depends on proper fit of the headset.
6.Headband Pressure Adjustments:
There are three pressure settings. Increasing the pressure will im- prove the seal between the earcup and the head for greater noise reduction. To change the pressure setting, remove the headset and fold the earcup inward as shown in Figure 3, then rotate the adjust- ment knob to the desired setting. Repeat for both earcups. Both sides of the headband should be set to the same pressure setting to keep the headband properly centered on the head.
