Call Functions

Speaker, Earpiece and Microphone
The earpiece is always turned on. The speaker and microphone are
always in opposite states, i.e. if the speaker is on, the
microphone is off, and vice versa.
You can toggle the speaker and microphone states by
means of the speaker key. The speaker icon appears on the display
when the speaker is on, and disappears when the microphone is on.
Hands free operation is not possible. You can call or receive a call,
and toggle the speaker on - for listening purposes only.
Note: When the speaker is off, you can see that you are being
called (the display will show "Incoming Call") - but there will be
no sound in the speaker.
