The test switch starts a test of the VOR/MB receiver. The built-in test equipment (BITE) circuits do a test of the VOR/MB receiver. The test results show on the common display, light emitting diodes (LEDs), and through the flight interphone speakers and headsets.

During the test, a self-test frequency generator gives a 75 MHz RF signal that has 400 Hz, 1300 Hz, and 3000 Hz audio signals. The bandpass filters find the audio signals and send them to the audio amplifier. The audio amplifier sends the audio signals to the REU. The REU sends the audio signals to the flight interphone speakers and headsets in the flight deck.

The BITE circuits monitor the condition of the output data of the VOR/MB receiver.

The VOR/MB receiver gets an air/ground discrete signal from the proximity switch electronics unit (PSEU). The VOR/MB receiver uses this signal to prevent a test in the air.

An internal nonvolatile fault memory (NVM) in the BITE circuits use the air/ground discrete signal. The NVM uses this signal to calculate flight legs.

Operation
The marker beacon antenna receives the marker beacon signals. The signals go to the VOR/MB receiver 1. The VOR/MB receiver 1 supplies this data: · Marker beacon audio to the remote electro

Audio Outputs
These are the marker beacon audio outputs: · Outer marker (OM) is 400 Hz, continuous dashes (- - - -) · Middle marker (MM) is 1300 Hz, alternate dots and dashes (-.-.-.-.-)

Marker Beacon Signal
The marker beacon antenna receives the 75 MHz signal and sends it to a 75 MHz filter in the VOR/marker beacon (VOR/MB) receiver 1. This filter tunes and rejects unwanted signals. The output goes to

Operation
When you push the test switch, the receiver does a check of the internal receiver operation and the interface with the NAV control panel. The test takes 48 seconds. This is the test sequence that s

Operation
To do a test of the VOR/MB receiver 1, select a VOR frequency and push the test switch on the front panel of the navigation control panel. FT shows for common display system indications. You must s
