The audio options available for your Smartbadge are the speaker mode, headset mode, and the handset mode.
The speaker button on the call screen controls how audio from the call is presented to the user.
Speaker Mode is activated by default, and the Speaker icon is highlighted. The audio is played through the Smartbadge speaker aloud.
In the handset mode the audio is played through the Smartbadge receiver, and people nearby cannot hear the call, and the Speaker icon is not highlighted. A handset icon is displayed on the Call status bar.
Headset Mode is automatically activated when a wired headset is connected. Speaker icon is not displayed when a headset is connected.
