A hearing aid (1) has means for entering or leaving a stand-by mode initiated by a remote control (14). During use, a dedicated stand-by command issued by the remote control is received and decoded in the hearing aid. When a stand-by command is recognized, a clock signal to the signal-processing parts (3) of the hearing aid (1) is disabled, effectively halting the signal processing. In the stand-by mode, the hearing aid circuitry draws very little power from the battery. Reception of a similar command in the hearing aid during the stand-by mode enables the clock signal to the signal- processing parts of the hearing aid, enabling signal processing. A method to manage the stand-by mode involves the step of calling a soft-boot routine when the hearing aid leaves stand-by mode and resumes normal operation.

Un dispositif d'aide auditive (1) a des moyens pour activer ou désactiver un mode de veille initié par une commande à distance (14). En utilisation, une instruction de veille dédiée émise par la commande à distance est reçue et décodée dans le dispositif d'aide auditive. Lorsqu'une instruction de veille est reconnue, un signal d'horloge destiné à des parties de traitement de signal (3) du dispositif d'aide auditive (1) est désactivé, arrêtant effectivement le traitement de signal. En mode veille, les circuits du dispositif d'aide auditive consomment très peu d'énergie de la pile. La réception d'une instruction similaire dans le dispositif d'aide auditive en mode veille active le signal d'horloge destiné à des parties de traitement de signal, activant le traitement de signal. Un procédé pour gérer le mode de veille implique l'étape consistant à appeler un sous-programme de redémarrage à chaud lorsque le dispositif d'aide auditive quitte le mode de veille et reprend son fonctionnement normal.
