How to adjust volume on the Headset Use the wheel at the center of the USB controller to adjust the volume. Turn clockwise to turn up and counterclockwise to turn down. You will hear a soft click in the headset each time you adjust the volume. When you reach maximum volume, the headset will beep twice as a warning. We recommend that you do not use the headset at full volume. HOW TO MUTE THE HEADSET Tap the mute button on the USB controller to mute the headset microphone. The mute light on the USB controller will change from green to red. To un-mute the headset microphone, tap the mute button again, and the mute light will change from red to green. Green when not muted Red when muted How to answer a call from your PC SoftPhone When a softphone call arrives, you will hear a ring tone in the headset. If you are using a Jabra-supported softphone, then answer by tapping on the hook-switch button on the USB controller; tap again to hang up when you are done. Softphone control requires that you install Jabra PC Suite (described later in this manual)*. For other softphones, use the native interface on your computer to answer and hang up.
