Cobra radar detector
Police usually do not leave their radar guns turned on all of the time. Indeed, most police officers prefer to use the "instant-on" technique to nab speeders. Instant-on works by leaving the radar gun in standby mode (no radar emissions) and then releasing a trigger button to instantly turn on the radar gun to measure a vehicle's speed.
You can check to see if your radar detector is detecting radar by putting it in Highway mode and then driving to a shopping center or other businesss location which has microwave radar automatic door openers. You should get either X band or K band alerts for these microwave automatic door openers. If you do not get any alerts for these door openers, and after having checked a few other locations which have microwave automatic door openers, then this would indicate that your radar detector is defective.
