Abstract
The invention relates to use of a double-acting communication device comprising a separate first user interface (1) which is substantially a telephone user interface including sound reproducing means, and a separate second user interface (2) which is substantially a keypad and display user interface. The first and the second user interface can be used at different times and simultaneously, whereby in the simultaneous use the communication device is substantially located on a table or in the lap and not at the ear like when using the telephone user interface only. Thus, when a simultaneous use is started, the sound reproducing volume is increased so that the user can hear the voice from the speaker (3, 5) even though the device is far from the user's ear. The second user interface (2) is located inside the device, so that it is preferable to locate the switch (15) affecting the sound reproduction volume so that it is attached to the opening mechanism of the device.
