I have a 8500 X50 Blue and my futiure soninlaw was driving on hwy 30 heading east about 100 miles before ft wayne indiana . very remote area , wide open farm land. He has a bad habit of cruising in the fast lane even if there are no vehicles around him. I must have told him atleast a dozen times over the last hour to get into the right lane , never stay in the left lane . So i see a state trooper heading west and I look real quick over my future soninlaws speed and his speedometer say 68-70 mph ...I am at a slight angle sitting in the passenger seat . I look at the escort it is on hwy and all bands are being monitored .(I thought ) . My soninlaw tells me that he looked n the rearview mirror and the ST is coming up fast and pulls us over . I ask the officer how he acquired us going 83mph . He said he had us on radar . As we were pulling out after being issued a citation ....i grabbed for the escort and io hit the programing mode so i can see what if anything is turned off. all are on except something that says POP. I tried turning the POP on but it does not appear to let me do so. I checked my other 8500 X50 when we got back home and it has POP and I can turn that off and on but i cannot turn the POP on in the other escort. What do you think happened . I have a few radar guns of my own and I checked the 8500 X50 when i got home and it worked fine on K,Ka and X . Any suggestions or anyone know why it did not pick it up ?
