i just got a 8500 and had a few questions. i got it from my sisters boyfriend, he works at circuit city and upgraded to an x50 and sold me his old 8500. my questions are, when it turns on it says "X alert Off" which is good, but does that decrease the range of K or Ka at all? and also, does anyone have an extra visor clip for a 8500. cuz he lost his and had it velcroed to his dash. and it also didnt come with a manual, obviously, or else i wouldnt be asking these questions lol , so are there any other tricks or modes that i need to knwo about? thanks.
