The back panel of the 9900, 9950, and 9951 contains both a speaker and a microphone that you can use
to send and receive audio signals over the GSM network; see Back Panel: 9900 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.
