SR 40 PRO Important repair hint In case that a receiver is unable to detect the transmitter signal, it may be that the indicated coil in misaligned. In this case the coil's core has to be adjusted for maximum audio output signal at lowest THD. After alignment the core shall be secured with wax.
SR 40 PRO Wichtiger Reparaturhinweis Falls ein Empfnger das Sendesignal nicht verarbeiten kann, ist unter Umstnden die gekennzeichnete Spule verstimmt. In diesem Fall muss der Spulenkern auf maximales NF-Ausgangssignal bei geringstem Klirrfaktor abgeglichen werden. Anschlieend ist der Kern mit Wachs zu sichern.
