2000) or Playback button (Windows 98) to open the Speaker dialog box (Windows
XP, 2000 and 98) or the USB Audio Device dialog box (Windows Me).

sources independently. Most levels are adjusted by the Volume sliders. Make sure
that the Volume sliders are set in the middle of the control and the Mute all box is
not selected.
• These sliders also allow you to adjust the amount of side tone you hear in your
headset. Side tone allows you to hear your own voice in the headset speaker, creat-
ing a more natural sounding conversation.

their own volume controls. These independent applications may override the Windows
controls and work independent of the GN 8120 USB sound controls. Consult your soft-
ware owner's manual if you have any questions.
