C-2000 DIGITAL AIRBORNE TELEPHONE SYSTEM
7.1.2.7.7 MicrophoneTXGain
It is possible to adjust the microphone audio gain. Because the digital handset incorporates a noise canceling microphone,
changing the microphone gain level can significantly degnide the sound quality and therefore it is not recommended that the
microphone gain level be adjusted. The microphone gain level does not have a standard default value and therefore is
adjusted individually at the factory. Depending on the software version in the digital handset, the Microphone TX Gain may
consist of one or two screens.
