LED Behavior:
Stays full on: this means the RROSD is running but not getting valid video signal from
the camera. Check camera cable
Blinks steadily: this is an indication that the RROSD is running properly and getting valid
video input. Check VTX cabling and make sure channels are set correctly. Check VTX antenna
to make sure there’s no short
LED not on when powered up: RROSD isn’t running. Check battery input cable and
make sure battery is charged
Wrong Video Mode: The garbled image below is an indication of RROSD video is different than
FPV camera’s. You will need to change video mode on one device to make sure they’re both
on NTSC or PAL
