Adjusting the volume when receiving a
Call
While calling, you can adjust the volume.

Note
• You may need to increase volume from your regular audio listening
source level. However, increasing the volume excessively may result in
feedback. Feedback is directly related to the volume. Turning down the
volume as low as acceptable, will reduce it. Positioning the microphone
in a direction away from the main car speakers (e.g. clipped on sun
visor) may also reduce feedback at high volume.
