Marker Beacon audio on 747-400

[Guest aa7373]

Hello, I've done a couple flights and noticed when I cross over a marker beacon I get the indication but no audio. I think I have audio selected but I'm not getting anything. Is there something I'm doing wrong?Thanks, John

MKR audio is selected on the audio panel...it does have to be on to hear the beacon, by default it is off.

Hello, How do you turn it on? Thanks, John

In the audio panel there is a very small APP button, push it and a yellow light will pop. At the right hand side of that tiny button there is a small rotating knob, turn it full right to the MKR position. That is all. And yes, the buttons in the audio panel are very very small and sometimes difficult to read.Jose Luis.
