4. Telephone
In order to make phone calls, the following re-
quirements must be met:
• An activated SIM card must be inserted.
• The phone interface must be switched on.
For a description of the phone interface keys and
especially the button, see chapter 13 "Phone
interface" on page 13-1.
Note: The phone interface keys are not function-
al when the device cover is open.
The Telephone application is started by pressing
the Tel. application button on the keyboard.
Some of the telephony operations explained here
can be made in many ways, for example, via the
phone interface.
Note the following Telephone features:
• Opening or closing the cover does not affect
active phone calls.
• If you have made a voice call via the phone
interface and you open the cover, the Tele-
phone application starts automatically. You
can continue the call after activating the
handsfree mode (see "Audio control").
• When you make a call via the communicator
interface (with the Telephone application), the
handsfree mode is activated automatically.
Audio control
The audio control enables you to adjust the vol-
ume level and to activate the communicator’s
loudspeaker for handsfree operation. The audio
control is available only when you have an active
call.
In the handsfree mode, you can speak and listen
to the phone from a short distance away when
the cover is open. This function is not available
when the cover is closed (except in a car instal-
lation). The Telephone setting Audio when cover
opened (in the settings group Other settings, see
”Telephone settings” on page 4-6), determines
whether the handsfree mode is activated auto-
matically after you open the cover. To activate
the handsfree mode manually, press the Audio
on command button.
After audio has been activated, the command
changes to Audio control. Pressing Audio con-
trol lets you adjust the speaker volume or turn
audio off. The indicator in the audio control view
shows the chosen volume level.
