15.10 Headset Profiles
In order to achieve optimal audio quality with the different headset types,
it is recommended that you select the corresponding profile. The default
setting is microphone on a boom, meaning that the audio is optimized for
using a headset with microphone on a boom.
To change the headset profile, do the following:
1. Press Menu, select , and press Select.
2. Select Headset and press Select
3. Select Mic on boom or Mic on cable, and press Select.
4. Press Back to save the setting.
If the pre-configured headset profiles do not match the headset in use,
or if the audio quality is low, it is possible to configure a new headset
profile. This is done in WinPDM or CPDM by the system administrator.
