Voice Communication
You can use the Dolphin terminal as a phone over the GSM radio.
Audio Modes
The back panel of the Dolphin 9900 contains both a speaker and a microphone that you can use to send
and receive audio signals over the GSM network; see Back Panel Features on page 3-6.
There are two audio modes:
Headset Headset mode is when you plug a headset into the audio jack and speak into the microphone. You
must use a 2.5mm plug; no other audio plug will fit.
Hands-Free Hands-free mode is when you use the back panel as a speakerphone. To switch the back panel to
speakerphone, in the Dialler, tap Settings > Speakerphone. The audio levels adjust appropriately
for speakerphone use.
Volume Control
Use the Dolphin keyboard to manually adjust the volume.
To raise the volume, press the Blue modifier key + up arrow.
To lower the volume, press the Blue modifier key + down arrow.
