Keyboard for a mobile radio telephone

Abstract

Abstract A control panel for a mobile radio telephone with a keypad and display section, where the keypad comprises a group of dialling keys and a group of function keys. The control panel is designed so that, making allowances for the peculiar features of its environment, it is clearly laid out and simple to operate. For this purpose, the group of function keys (7) contains at least two keys (T1, T2), by means of which, starting from a normal functional level (I), in which the dialling keys are used to enter dialling codes, further functional levels (II, III, IV) can be activated, in which other functions are assigned to the dialling keys. By means of a further key (T3) within the group of function keys (7), special functional areas can be activated within the relevant functional level. The respectively activated functional levels and/or functional areas can be visually represented in the display section (6). <IMAGE>
