Thread: Garmin RINO 650

Check CTSS, its been a while since I have used a 650, but on the 750 having CTSS on or off affects calling/recieving.
Hopefully it should be right there in the radio screen.

From memory I think you need it on to call out, but you can still recieve with it off. When I get back to work on Monday I will be able to remind myself what the correct setting is for CTSS, I usually just keep adjusting it until it works.
