  18. Dispositif de mise à feu selon une des revendications 14 à 17, caractérisé en ce que pour le codage des données on utilise la méthode Audio Frequency Shift Keying (AFSK).
  19. Procédé pour la mise à feu de détonateurs électriques ou électroniques déclenchables par radio, à l'aide d'un dispositif de mise à feu comportant au moins une unité de déclenchement à laquelle au moins un détonateur est connecté, et un appareil de mise à feu, éloigné dans l'espace de l'unité de déclenchement, qui communique avec l'unité de déclenchement par des signaux radio, notamment selon une des revendications 1 à 18, caractérisé en ce que la mise à feu des détonateurs ne peut avoir lieu qu'après annulation successive de sûretés, l'annulation d'une sûreté étant suivie d'une étape de procédé nécessaire au déclenchement de la mise à feu, et le résultat de cette étape devant satisfaire une condition possible pour l'annulation de la sûreté suivante, et en ce que la mise à feu du détonateur ne peut avoir lieu que lorsque toutes les sûretés sont annulées et, lorsqu'une étape de procédé ne peut pas être lancée ou n'aboutit pas à un résultat prédéterminé, l'étape de procédé suivante ne peut pas être lancée.
  20. Procédé selon la revendication 19, caractérisé en ce qu'on retire de l'unité de déclenchement un support de données qui contient un code d'identification identique à celui de l'unité de déclenchement ainsi que des informations sur l'unité de déclenchement et les détonateurs connectés, en ce que les données du support de données sont inscrites dans une mémoire de l'appareil de mise à feu et en ce que la disponibilité en émission et dans le cas d'une communication bi-directionnelle, également la disponibilité en réception sont initiées.
