Operational Checkout
NOTE:
Because the Radio Adapter is designed to interface with commercial or public service/safety transceivers,
your testing may affect other radio services. Verify frequencies and operating procedures before attempting
to transmit on unknown radios.
1. Verify that aircraft power is present only on Pin 1 (28 VDC) or pin 2 (14 VDC).
2. Apply power to the avionics and tactical transceiver.
3. Verify that the receive audio from the tactical radio is present in the aircraft audio sys-
tem when selected.
4. With the transceiver connected to a dummy load, or to an antenna, and operated by
properly rated personnel, press the aircraft PTT, and verify that the transceiver
switches to transmit mode.
5. Verify that there is microphone audio through the system by making a radio check
with an appropriate facility.

examining the installation to see that no mechanical interference exists. Verify that the
cables are secured to the aircraft structure in accordance with good practices, with ade-
quate strain relief. Ensure that there are no kinks or sharp bends in the cables. Verify that
the cables are not exposed to any sharp edges or rough surfaces, and that all contact
