Put the headset on and adjust the ear pad to fit snugly over your ear.
Rotate the electronic module up or down to position the microphone near your
mouth.
Make final adjustments with the flexible boom so that the microphone is
positioned correctly. Position the microphone as close to your mouth as
possible, but outside of your breath stream. It should be facing your upper lip,
and not touching anything (for example, clothing, skin, or facial hair). The microphone should be approximately 1" from the corner of your mouth.
Use the cable clips to fasten the wire to the collar and belt to prevent snagging.
