and then the * button.

Volume control
The volume of the handset can be adjusted during a call by
pressing the navigation directional buttons (7).
To activate hands-free/speakerphone, press the right
function button (8) during a call.
Warning: Excessive noise can damage your hearing! Listen
to music at an appropriate volume and do not hold the device
close to your ear, especially when using a speaker!
Antenna placement
At the lower rear, the device has internal antennas for
receiving and transmitting. Do not cover the locations where
the antennas are located. When talking, hold the device at
least 2-3 cm away from your body. This will reduce the
amount of electromagnetic radiation absorbed by your body.
Covering the antennas also affects the intensity of the
broadcast and therefore the battery life.
