Raymarine RL70
Hi folks. I've got a Raymarine RL70 radar on my rib and when I turned it on the other day there was no picture on the display. The first thing I did was a master reset although I didn't think this was going to solve the problem but a reset was long overdue! When my gain, tune, rain and sea clutter are set to auto I have nothing on my screen. When I adjust the gain up to 92% an image appears. Does anyone know why it's doing this as I know this isn't as fine tuned as it could be?
Thanks in advance
