Connecting the headset
Simply plug the headset into the USB port on your PC.
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.
Using your headset

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.
Checking audio settings
1 Ensure Microsoft®Lync™/Microsoft® Office Communicator is running on PC.
Check that the C435-M is set as the audio device in audio device settings under tools.
2 Place a call using Microsoft Lync/Office Communicator.
3 For non-Lync/Communicator applications, confirm the speaker and microphone settings for the
PC softphone are set to Plantronics C435-M.
• To check in Windows 7:
Go to Control Panel -> Sound -> Playback tab, and set the Plantronics C435-M device as both
the Default Communications Device and the Default Audio Device. In the Playback tab, this is
indicated by the green tick mark.
• To check in Windows XP:
Go to Control Panel -> Sounds and Audio Devices, and in the Audio tab set the Plantronics C435-M
for both the Sound playback and Sound recording sections. In the Voice tab, select the
Plantronics C435-M item for both the Voice playback and Voice recording sections.
IMPORTANT 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
