(Click image for a larger view) | The MB10-is a 3-light 75 MHz Marker Beacon receiver and indicator. This provides the necessary Marker Beacon lights and audio indications necessary for an Instrument Landing System (ILS) approach. A switch labeled Hi/Lo/TST allows the pilot select high or low sensitivity as well as test and mute modes.
Note: The MB10R has provisions for remote mounting the Marker Mode selector (Hi-/Lo-Test/Mute). This must be an On-Off-Momentary On switch. Connect Pin 15 to ground to place the unit in High Sense, and momentarily ground Pin 13 to mute the marker audio. Holding this pin low for 1-second will test the lamp circuits.
*In certified aircraft, the warranty is void unless the product is installed by a PS Engineering dealer.
