I've read the directions on the V1's site and read through a few threads here but I still can't figure out how to do it. I've had my V1 for a few months now and left it untouched to get a feel for all the functions. I have decided that its time to program how I want it. I have 3.863 and turned X-band off. I'm trying to get the K-band to mute for 20 seconds and un-mute at 4 bars. If I'm reading the chart correctly, it says b (UP) C (down) d (up). I tried this and kept it on (L), but when I hit a K-band, I could still hear it loud and clear till I manually mute it. Am I doing something wrong here? Any help would be much appreciated. Thank you.
