A friend of mine got AIR PATHWAYS Series 300 intercom. Was not able to locate any manuals or schematics. If somebody has any paperwork in digital format please contact me. Or direct to the source. Needed very much.
It doesn't need to be written in Chinese or a Slavic language Any info appreciated. I was trying to google the AIR PATHWAYS company but can not find them.
Thanks Luke,
I googled that book, looks like the only source on the Web. Will refer it to my friend. Kind of steep price for pins callout but it is what it is. Nothing is cheap in avionics.
