Les emetteurs sont equipes du systeme de reduction des sons parasites«HiDyn» ce qui permet autan! de reduire les bruits parasites que d'amelio- rer le rapport .signal/beuit.Combine avec un recep- teur equipe egalement de ce systeme (tel que le
EM 1036), on obtient un eircuit de transmission d'uneextraordinaire securite de lonctionnemen! et
d'unequalite de transmission superieure.
