tematically switching the unit on and off, while monitoring the other avionics and electrical equip-
ment on the aircraft.
2.11 Internal Recorder Checkout (Optional units only, -0200 and -0400)
With headset plugged into pilot’s side jacks, tune COM 1 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 the pilot’s headset, and only be incoming transmissions from the trans-
ceiver selected in the mic select switch.
Depress the panel or yoke mounted playback switch, and verify that messages play, in the order received.
Repeat for other installed transceivers.
2.12 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.
