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.
