Echo when using the headset
If you are having echo problems while not on a call (you are wearing the headset, it is active, but you are not currently on the phone with anyone), there are 3 ways to counteract this:
-When you are done with a call, you can click your Multifunction button on your headset (middle one inbetween the volume controls).
-Move the microphone away from your mouth when you are not on a call.
-A more permanent solution: decrease the sensitivity of your microphone. To do this, click and hold the increase and decrease volume buttons on your headset ( + & - ) for 3 seconds. Let the buttons up after 3 seconds and push the lower volume button 2 or 3 times. Wait 6 more seconds and it will beep at you. After you have done this, make a call to someone in the office to be sure the sensitivity has not been lowered so much that others can?t hear you. Read More At : GN 9120 Professional Headset...
