Abstract

La présente invention concerne un dispositif de communication sans fil présentant un ou plusieurs modes de fonctionnement prédéterminés des touches pour que la fonction associée à la touche puisse être effectuée. Par exemple, l'activation d'une touche d'alimentation sur (114) le dispositif de communication sans fil peut être activée intentionnellement ou par inadvertance. La dispositif de communication sans fil nécessite une activation de la touche choisie présentant un mode prédéterminé de fonctionnement pour qu'elle soit considérée comme étant un acte intentionnel de l'utilisateur. Les modes de fonctionnement prédéterminés peuvent varier selon les différentes conditions du dispositif de communication sans fil. Les modes de fonctionnement prédéterminés peuvent nécessiter une activation continue pour une durée prédéterminée, une activation multiple de la touche choisie dans une durée prédéterminée, une activation simultanée d'une pluralité de touches, une activation séquentielle d'une pluralité de touches, ou autres. Le dispositif de communication sans fil peut aussi être utilisé pour afficher une confirmation de requête par l'utilisateur d'une fonction choisie.
