How do I use a wireless headset?
Using a wireless headset
Before using your Microsoft® LifeChat wireless headset, install the LifeChat software from the CD included with your headset and connect the wireless receiver to a powered USB port.
Charge the headset.
Turn on the headset and lower the volume.
Put on and position the headset.
Adjust the microphone. Position the microphone's flexible arm so that the microphone is approximately one inch (3 centimeters) from your mouth. Move the arm to one side of your mouth to prevent transmitting the sound of your breath while you are on a call.
