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 select marker beacon audio on at least one of the ACPs to hear the audio tones. All the marker beacon audio tones come on in the flight compartment when you do the test. The audio tones come on continuously and you hear the outer, middle, and inner at the same time.

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

Monitor and Test
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 diode

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
