3.3.2 CAR KIT SWING/OFFICE SET SWING (theory)

The four-step CAR KIT SWING/OFFICE SET SWING tuning is used to set the
contrast of the microphone amplification/speaker attenuation swing. In the
following figures the swing position while listening to the Car Kit or Office Set is
indicated by a solid line and the position while speaking into Car Kit or Office
Set the indicated by a dotted line.
a. With a tuning value of 4 it is possible to obtain the smallest difference
between the amplification and attenuation of the microphone and speaker. This
means that the connection is almost bidirectional. If the HF-function easily
creates feedback, decrease the value of the CAR KIT SWING/OFFICE SET
SWING. By turning down the volume it is possible to reduce the occurance of
feedback.
