    When I make a call, the recipient cannot hear me. I tried to hold down the middle button for six seconds, then hit the + 3 times and it did not work.

Hold down the middle button on your headset for 6 seconds until you hear a series of beeps. Then hit the + sign about 2-3 times and then press the middle button again to disconnect. This should fix the issue. Make sure to call someone to test this as you may have just turned the volume up way to high. If that is the case, then you need to repeat this process using the - button instead of the + button.

New Phone Causing Echo

It sounds like your microphone volume is too loud. Get someone on a call with you so they can tell you how it sounds as you adjust it. Turn down the mic volume by pressing the + & - buttons on the earpiece together once which puts the earpiece into mic adjust mode. Then decrease the mic volume by pressing the minus button a few times until it sounds right. The earpiece will automatically revert to normal mode within a few seconds.
If this doesn't work it may be that you need to adjust the compatibility setting for the new phone. This is the small black dial on the base station. The most common setting is 'A' but you may need to experiment with other settings for that phone.

GN Netcom GN 9120 - can't hear

Hi There, I had the same problem with a headset one of our call centre reps were using. It's usually due to some one fiddling with the button. I got it working by removing the battery from the headset then resinked the headset to the base unit. Hope it works for you

Incoming alert

Generally you will get a ring in the headset when a call is detected by the lifter that you use or if you don't have a lifter then you would have to use the little microphone that comes with the unit and affix that to the speaker on your phone so that your GN 9120 knows when to alert you of a call.

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.
