So i was driving home a few minutes ago. During the ride i was getting some bleeps of Ka (the LEO ended up being about .75 miles away on a highway that was higher than me (KA)). I was approaching his location (common speed trap) and the my pro 78 suddenly stopped beeping. I looked up and noticed that the screen was still showing a 4-5 bar signal and the two LEDS were just static-on (when they should be flashing).
later on when I passed a Ka speed sign the detector worked normally with normal distance.
Why did my pro 78 just freeze like this. This did happen within 4-5 mins of turning on my car so it was still very cold in the car (27 F at min).
