With headset plugged into pilot’s side jacks, tune aircraft radio to local frequency, such as FSS or ATC
ground.
Select Com 1 on mic selector switch, and record at least five incoming radio transmissions.
This audio should only appear in one side of the pilot’s headset, and it should be radio (or sidetone) traffic.
Depress the panel or yoke mounted playback switch, and verify that all five messages play, in the order
received.
2.9 Final
Inspection
Verify that the wiring is bundled away from all controls and no part of the installation interferes with air-
craft control operation. Move all controls through their full range while examining the installation to see
that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accor-
dance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the
cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and
that all contact points are protected from abrasion.
