Microphone placement

Proper microphone placement is important for clear communica-

tions. With the headset on your head, make these adjustments:

1.

Grasp the boom with your fingers and move the microphone up

or down so it is level with your mouth (Figure 17).

2.

Pull the microphone in toward your lips. Position the microphone

with its label side facing in. Though it will be slightly off center,

the microphone should be

1

inch from the opening of your lips.

Make sure the broad side of the microphone is facing your lips.

Do not purse your lips.

Operating the battery powered headset

If your headset is battery powered, read the control information

below. If your headset is aircraft powered, refer to “Operating the air-

craft powered headset” on page 23.

The battery powered headset uses

AdaptiSense

™ headset

technology to supply the power your headset needs at any given

time. Smart shutoff turns off the circuitry several minutes after you

remove the headset.

This maximizes available energy for longer life from the two batteries.

A tri-color LED provides real-time battery status. Its brightness is

adjustable for day/night operation.
