A communication device (10) includes a power key (40) located on an outer surface of the housing which may provide multiple functions, but is resistant to initiation of undesired handset functions. Control circuitry (50) within the communication device may be configured to ignore any actuation of the power key (40) with a duration less than a determined time period. The control circuitry (50) performs a first function if the power key is depressed for a first duration (T1), and performs a second function when the power key is depressed for a second duration (T2). For example, depression of the power key (40) for a short period of time may silence an incoming call alert, whereas depression of the power key for a longer period of time will turn the communication device on or off.

L'invention concerne un dispositif de communication (10) qui comporte une touche interrupteur (40) située sur une surface extérieure du logement et permettant d'effectuer des fonctions multiples, mais empêchant le lancement de fonctions indésirables du combiné. Des circuits (50) de commande situés à l'intérieur du dispositif de communication peuvent être configurés pour ignorer toute pression sur la touche interrupteur (40) d'une durée inférieure à une période prédéterminée. Les circuits (50) de commande lancent une première fonction si l'on appuie sur la touche interrupteur pendant une première période (T1) et une deuxième fonction, si l'on appuie sur la touche interrupteur pendant une deuxième période (T2). Par exemple, un appui de courte durée sur la touche interrupteur (40) peut acquitter le signal d'appel, alors qu'un appui plus long aura pour effet de mettre sous tension ou hors tension le dispositif de communication.
