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.
b. With a tuning value of 1 it is possible to obtain the greatest difference
between the amplification and attenuation of the microphone and speaker. This
means that the connection is almost unidirectional.
The factory setting for the CAR KIT SWING/OFFICE SET SWING is 3.
