I might be completely ignorant by asking this question, but what does it mean when the V1 displays a signal but does not say what type of band it is? The sound is also different than the other bands. It is a very short single 'scratchy sounding' 'DENT' (sorry for my lack of V1 sounds speak). I have K and X turned off.
Most of the time I can find another car floating around me with a detector that seems to look like a cheap model of some sort. It is always a very faint single-dot signal on the display. I always assumed it was a radar signal from other detectors.
I can't find any mention of this in the manual or on the forums. Am I just going crazy?
