How do I make a test call on Microsoft Office Communicator (MOC) with my Plantronics headset?
Please note the headset must be plugged into your computer first. Ensure Microsoft Office Communicator is running on your PC.
Some MOC headsets do also have in-line volume controls. You can fine tune the listening volume on the headset by using these, and in the case of the Savi™ Go headset you can use the call control button to adjust the volume levels as below:
NOTE: Do not press the call control button in when adjusting the volume otherwise the call can be ended accidentally.
NOTE: For your safety, do not use headset at high volumes for extended periods of time. Doing so can cause hearing loss. Always listen at moderate levels. For more information on headsets and hearing visit:
