OPERATION
Power
The MB10 is active whenever
the avionics bus is energized.
Marker Beacon Operation
The Marker Beacon Receiver
uses visual and audio indicators to
alert you when the aircraft passes
over a 75 MHz transmitter.
The Blue lamp, labeled "O”, is
the Outer Marker lamp and 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 Beacon.
The Amber lamp, labeled "M”,
is the Middle Marker lamp and is
coupled with a 1300 Hertz tone. It is
keyed alternately with short 'dot' and
long 'dash' bursts at 95 combinations
per minute.
The White lamp, labeled "I”, is
the Inner marker and has a 3000Hertz 'dot' tone. The lamp and tone
will be keyed at a rate of six times
per second.
The audio from the Marker Beacon Receiver is provided to the aircraft audio selector system. To adjust the volume level, there is a service adjustment located on the top of
the unit.
A toggle switch is used to set
the receiver sensitivity and to test the
indicator lamps. Use "HI" sensitivity
initially. This allows you to hear the
outer marker beacon about a mile
out. Then switch into Low Sensitiv-
ity mode. “LO” sensitivity gives you
a more accurate location of the Outer
Marker. Holding the MKR switch
down for two seconds activates
marker test lamp, labeled "T/M" and
illuminates all three lamps simultaneously to assure the lamps (internal
and external) are in working order.
TST does not activate MM autopilot
sense output. Releasing the button
returns to the low sensitivity.
Pressing the marker mode select
(to “T/M”) for two seconds will also
cause the marker audio to mute for
that beacon. The next beacon received will re-activate the audio.
Warranty and Service
Warranty
In order for the factory warranty
to be valid, the installations in a certified aircraft must be accomplished
by an appropriately rated FAA- certified avionics shop and authorized
PS Engineering dealer. If the unit is
being installed by a non-certified
individual in an experimental aircraft, a factory-made harness must
be used for the warranty to be valid.

warranty period, PS Engineering,
Inc., at its option, will send a replacement unit to the PS Engineering dealer, if the unit should be determined to be defective after consultation with a factory technician.
PS Engineering will not ship to the
end user under warranty, unless au-
