Help! My iFly 740 has taken to beeping at me: 10 beeps, then a pause for maybe half a minute and 10 more beeps. Repeat.
But it only beeps when it's connected to airplane power. It quits beeping if I unplug it, and it doesn't beep when connected to the car or the house current.
At least, I THINK it's the 740. What else could it be, when that's the only gizmo in the airplane that's powered up?
I have system sound muted and the volume turned all the way down and all other alerts t urned off.
During the last two flights it kept up the beeping all the time, from master ON to master OFF. I could hear it even in flight, despite a very good headset. No, it's NOT coming through the intercom. It's coming from the 740's internal speaker. When I tried it today, it started beeping as soon as the 740 began powering up.
I'm probably just missing something simple and basic--but I sure am missing it! I hope someone can help.
