I have an RX65 unit, that I have had for years now, this however is something new (that's on the display) that I've never seen before and wanted to know if anyone knows what it is.
I noticed about 200 yards from my house, that the radar was going off with an X3 on the display, this is nothing unusual. There is a cop station close by and various home alarms that set it off. What was unusual is that every other beep, the 3 was replaced with a small red circle at the top.
So it'd go: X3-X*,X3,X*, etc, etc.
What's up with that circle and what does it mean???
