Abstract

A mobile telephone has a plurality of user adjustable operating characteristics, such as the volume of an output signal, the ringing volume, and the generation of tones. When moving from one environment to another, such as from an indoor environment to an in-car environment or an out-door environment, it is preferable to modify a plurality of these operating characteristics. In order to facilitate the modification of the plurality of user adjustable characteristics each group includes predetermined values for all these characteristics and the selection of a particular group results in a plurality of characteristics being modified simultaneously. Thus, when moving from one environment to another, a user is only required to make a single menu selection, resulting in a plurality of operating characteristics being modified simultaneously. For example, when moving into an in-car environment, the output volume can be increased, ringing tone volume can be increased and a call transfer function, if previously selected, can be disabled.
