Operation with headphones Stereo headphones (impedance > 32 ) are connected to the large jack. Lockable cover on receiver In order to reach the operating elements, a slide (S) is located on the right side of the unit. This protects the operating elements against unauthorized or accidental use. It is secured with a set screw (M), which is screwed in completely in order to open the slide. After removing the slide two potentiometers are accessible: · The connected hearing aid microphone or the microphone built into the receiver are turned down for the duration of speech transmission. This enables the signal of the speaker to be given preference at the wearer of the receiver. Setting automatic fade-in This adjustment is made exclusively by the hearing aid dealer! an adjuster (E) for the reduction depth of the automatic fade-in is located at the top behind a hole in the housing.
