R7003SB Channel Mode setup
 

Mode D: Port 1 - CH1, Port 2 - CH2, Port 3 - CH3, Port 4 - S.BUS = (4) red blinks per the manual. When I depress Link/Mode button, my 7003 toggles through the various modes jumping from Mode C (3 reds) to Mode E (1 green) without presenting Mode D.

Any guidance on how to set to Mode D?

Thanks

Press and release the button and wait about 1 second or so before you press it again. It may be misinterpreting the button presses. If you cannot get into Mode D, then send the receiver to the service center to be checked out.

Firstly, thank you very much for your guidance!

When going back to give it another go, I realized that I had actually installed the R6303SB, not the R7003SB as I had thought. It was operating as designed. Switched to Mode/Group 7 and everything is working :-)

Cheers

Wonderful!
