I got a v1 recently. I adjusted the settings for the k band auto mute for 5 seconds. While in little L mode it works like it is supposed to. However, i leave my unit in BIG L mode to eliminate x band sensitivity a bit. When in BIG L mode when i encounter k band signal even just 1-2 bars i do not get the auto muted volume. IT is full volume. It works like it is supposed to in logic but not advanced logic. Any ideas?
