switch allows proper transmission on the selected transceiver.
8. Verify that the Com 2 receiver to be selected and heard. Verify operation on Com 1 from the pilot
position.
9. Repeat for Com 2
10. Verify that the split mode can be invoked from the MFD, and verify that the pilot can transmit and
receive on Com 1, while the copilot transmits and receives on Com 2.
11. Verify proper operation of all receiver sources by selecting them using the appropriate means. The A1
and A2 indicators illuminate to show which navigation audio source is in use.
12. Verify that the appropriate transmit indicator is active when either push to talk is keyed.

14. Verify that the audio selector panel system does not adversely affect any other aircraft system by sys-
tematically switching the unit on and off, while monitoring the other avionics and electrical equip-
ment on the aircraft.
2.14 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.
