Marker Beacon Operation (9)
The Marker Beacon Receiver uses vis-
ual and audio indicators to alert you
when the aircraft passes over a Beacon
transmitter.
The Blue, Outer Marker lamp has an
associated 400-Hertz 'dash' tone. The lamp and tone will be keyed at a rate of
two tones/flashes per second when the aircraft is in the range of the Outer
Marker.
The Amber, Middle Marker lamp is coupled with a 1300 Hertz tone, keyed
alternately with short 'dot' and long 'dash' bursts at 95 combinations per min-
ute.
The White, Inner marker lamp has a 3000 Hertz 'dot' tone, and will be keyed
at a rate of six times per second.
Marker Beacon Receiver audio can be heard by selecting the "MKR" push-
button switch. There is a service adjustment located on the
top of the unit, labeled MKR VOL, to adjust the volume if
desired.
The MKR button located next to the indicator lights is used
to set the receiver sensitivity, to test the indicator lamps, and
mute the marker audio.
Pressing the MKR button for one second will cause the marker audio to
mute. The next beacon received will re-activate the audio.
Holding the MKR button for one second also activates marker test, labeled
"T/M" and illuminates all three lights simultaneously to confirm the lights
(internal and external) are working. Releasing the button returns to the last
sensitivity.
