Stereo / Mono Setting.
Whether you should use a Mono or Stereo setting
depends on your aircraft’s avionics. Incorrect setting will
result in communication being heard in only one side.
Stereo /Mono setting does not eect the audio from your
auxiliary sources.
For most general aviation planes, Mono setting is
required. To change this setting, please remove the
battery compartment, any batteries and change the
switch position using the gure below.
