Abstract

a. Dispositif d'accord automatique et manuel. b. Dispositif caractérisé par des repères mobiles en fonction de la position de l'émetteur à prérégler sur le cadran ainsi que d'un organe de réglage mobile entre une position correspondant à la plage FM et une position correspondant à la plage AM; chaque repère ayant la forme d'un cavalier muni de moyens de contact pour une bande résistante en fonction de la fréquence de l'émetteur correspondant. c. L'invention concerne notamment le préréglage de postes de radio.
