Wearing the headset
The headset comes fitted with the ear loop and medium ear gel.
1 To wear the headset, simply place the ear gel in your ear with the loop at the top of your ear
and rotate the microphone boom forwards. The microphone should be pointed to the corner of
your mouth. If it cannot be comfortably positioned there, you can rotate the ear loop and gel to
fit your ear.

2 The headset comes configured with the microphone on the left but it’s very simple to switch
the microphone to your right ear if you prefer that configuration. Simply pull the ear loops off
the speaker, rotate them and replace.
3 The headset comes with medium ear gels already fitted. If you find that the headset is
uncomfortable or unstable, you can easily change the gel to suit. Simply unpeel the gel that is
on the speaker and replace with a different one.
Large Small
4 Once the headset is positioned on your head, adjust the flexible boom to place the tip closer to
the corner of your mouth. The boom can be shaped to follow the curvature of your face.

5 For those users who do not want speakers in both ears (all the time or just occasionally),
you can disconnect the second speaker at the connection point shown below. This will
automatically change the headset from stereo to mono (and vice versa when reconnecting).

*The headset is supplied with a cover for the connector when configured as a mono headset
In-line controls

Volume Volume up and down are available.
Mute A single press of the mute button will mute the microphone. A red LED will be on
when you are muted. Pressing this button again will take the microphone off mute.
NOTE For call control and other features, download Plantronics software at
http://www.plantronics.com/businesssoftware.

of time. Doing so can cause hearing loss. Always listen at moderate levels. For more
information on headsets and hearing visit: plantronics.com/healthandsafety.

Clothing clip
This will reduce the weight of the cable on the capsule for greater comfort. It will also reduce
the tug on the capsule from the USB cable if you move away from the PC whilst wearing the
headset.
Stereo cable tidy
This can help reduce cable tangle. When you remove the headset, zip up the cable and you
reduce the risk of the headset cable becoming tangled. This is also advised when wrapping the
cable to stow in the case.
