Problem  
Solution  
I cannot hear caller.  
• The USB headset is not set as the  
default audio device. To change audio  
setup, refer to the Microsoft Office  
Communicator user guide.  
• Listening volume is too low. Press the  
volume up button on the headset.  
Callers cannot hear me.  
• Headset is muted. Press the mute  
button on headset to unmute the  
microphone.  
• Headset microphone boom aligned  
incorrectly. Align the headset boom with  
your mouth.  
Adjusting Volume  
• The USB headset is not set as the  
default Voice device. Use the Voice  
settings in Windows under Sounds  
and Audio Devices to select “Blackwire  
C210-M/C220-M” as the voice device.  
To increase listening volume, press the volume up (+) button. To decrease listening  
volume, press the volume down (–) button.  
To adjust the listen or speak volume of the Microsoft Office Communicator,  
please refer to the softphone user documentation. It is recommended that the volume is  
adjusted on the inline control and not the Windows volume control.  
Sound in headset is distorted.  
I can hear echo in headset.  
• Lower the listen volume on your  
softphone until the distortion disappears.  
To adjust the speak volume of the audio device on the computer, use the Sound  
and Audio Device section on the Control Panel.  
• Adjust volume on headset.  
The other headset I was using to  
listen to music does not work any  
more.  
• The USB headset will set itself as the  
default audio device in Windows. Use  
the Audio settings in Windows under  
Sounds and Audio Devices to change  
the device used for audio.  
My headset stops responding  
to button presses.  
• When a PC goes into standby or  
hibernation, the USB headset no longer  
is powered on. Be sure your PC is in an  
active state.  
Muting a Call  
To mute the microphone during a call, briefly press the mute button. When muted, the  
Mute LED will be lit.
