Marker Beacon Operation (9)
The Marker Beacon Receiver uses visual
and audio indicators to alert you when the
aircraft passes over a Beacon transmitter.
The Blue, Outer Marker lamp has an asso-
ciated 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 select-
ing the "MKR" push-button switch. There is a service
adjustment located on the top of the unit to adjust the
volume if desired.
The MKR button located next to the indicator lights is
used to set the receiver sensitivity and to test the indicator lamps 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 acti-
vates marker test, labeled "T/M" and illuminates all three lamps simultane-
ously to confirm the lamps (internal and external) are working. Releasing the
button returns to the last sensitivity.
Split Mode
To activate the split mode, push both the COM 1
and COM 2 XMT (bottom) buttons at the same
time. All four indicators will come on. In the
split mode, the pilot is on COM 1, while the
copilot is on COM 2.
