I went from a vx1 RDP-139 ser# 6902. to a RDP-149 cmapNT. everything is working fine except when I try to adjust the GAIN on the radar. I'm not sure if I entered the wrong type of radar when setting it up but I've tried 3 different types so far in setup and they all have the same issue with the Gain. It's stuck at Auto-rough gain 1. when I turn the knob to select something else it just beeps.
