2.11 Cellular Interface Checkout
When a wireless telecommunication system is installed and the unit configured for duplex, a dial tone will
appear in the headset of the pilot when the COM 3 Xmt selector activated. In “ALL” intercom mode, a dial
tone will be heard whenever the copilot or passenger’s hook switch is closed.
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 accord-
ance 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.
