2. Adjust the headset band until it rests with almost no pressure on your ear and the top of your head.

If the headset is loose, remove it and adjust it inward slightly to tighten it. If the headset is tight, gently pull the headset band out to loosen it.

3. Holding the headset in place

(as shown), adjust the microphone boom until it is about even with your chin. Experiment until you find the most comfortable position.

4. Route the headset’s modular cord through the lapel clip’s channel and attach the lapel clip to your clothing. Leave enough slack in the cord so you can move your head without pulling the headset.
