20.4 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, Mic on cable or Hearing protection, and
press Select.
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 CPDM3 by the system administrator.
