You can use the Dolphin terminal as a phone via the GSM radio.

There are two audio modes: Speakerphone and Headset.

Use the microphone on the front panel and the speaker on the back panel to operate the GSM 
phone in Speakerphone mode. Speakerphone is the default audio mode.

Headset mode is when you use a headset with earplug for audio input and the microphone for 
audio output. 

You can use two kinds of headsets: a mechanical headset or a Bluetooth headset.

For mechanical headsets, you must use a 2.5mm plug; no other audio plug will fit in the audio 
jack on the side panel; see 

speakerphone to headset mode automatically upon the insertion of the plug and returns to 
speakerphone when the plug is removed. 

For a Bluetooth headset, you need to activate the Bluetooth radio on the terminal and connect 
to the Bluetooth headset; for more information, see 

 The terminal switches from speakerphone to headset automatically when the Bluetooth 

headset is connected and returns to hands-free mode when the Bluetooth headset is 
disconnected.

Use the Dolphin keyboard to manually adjust the volume in all audio modes.

To raise the volume, press the Blue modifier key + up arrow. 

To lower the volume, press the Blue modifier key + down arrow.
