Instructions for DCS Remote Commander faculty reset.
Page 10 of my manual:
Turn off power if on
wait 15 seconds
turn on power: the engine should be dark and quiet
Press no other buttons
Press SND
Press DIR
Press "-" (on the gray rocker in the center of the remote. Also is the speed down button.)
The engine will give a two honk response and will be sitting on the track running
The engine has now been factory reset, and is ready to run with your DCS Remote Comander system.
