Why does the microphone uplink audio sounds quiet when in handsfree mode?
Depending on how loud the background noise is where the IsatDOCK is being operated, the unit's advanced DSP echo canceller may try to limit the microphone uplink audio to reduce feedback. In these instances it is recommended that users reduce the speaker volume by pressing the down arrow button on the lower keypad interface. Once the speaker volume has been reduced, the microphone uplink audio quality will improve.
