Microphone placement
Microphone placement is important for clear communications. 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.
2. Pull the microphone in toward your lips. Position the microphone with its talk
side facing in (indicated by label). Though it will be slightly off center, the
microphone should be 1/2 inch from the opening of your lips.
