In most cases, laser falses can be attributed to other sources of laser or interference from other devices, even your car.  Here are some examples of common sources of laser falsing;

  • RF Interference from something on/in the car, such as windshield wipers, engine noise at high RPM or hard acceleration, power windows/doors. These sources of electronic noise can trigger your detector.  
  • Real laser sources (for example; Facial recognition on phones, Cars w/ hand gesture systems for changing the radio station and performing other vehicle functions, airport equipment, toll booths, in vehicle technologies like lane assist or cruise control.
  • Some horns can cause an interference alert. This can be tricky to eliminate, short of replacing the horn.
  • Mottled, bright sunlight or sun on the horizon.

All of the above mentioned issues can cause your detector to react.  Here are some suggestions for reducing or even eliminating these pesky false alerts:
  • Try to mount in a different location (you may be able to move away from the source and quiet the detector down)
  • Try using in different cars (if it doesn’t happen, it’s RF from the car you are getting the alerts in.... again, try changing the mounting location)
  • Find out if it’s often in the same place (airport, etc), or random. If it's always or often in a particular place, it's a safe bet there is an unknown source of laser there. You can try to lock it out on GPS enabled devices.
  • Has anything changed in your car?  A new phone, radio, GPS device?  This may be the source, if so.  Try turning it off to see if the alerts clear. If they do, try using the device again, but move it as far away from the detector as possible.  
  • If it happens in multiple cars, repair may be in order if not phone interference.  You could have a defective laser sensor or a scratched lens.
  • Another option, if nothing else seems to do the trick, is a laser modification where we slightly reduce the laser sensor's sensitivity at the factory.  This is covered under warranty or our T2/T3 repair service if out of warranty.  This is successful in most cases, and usually reduces the unwanted alerts. However, it does involve a slight decrease in laser performance.  This does not generally have a big detrimental impact, so it's a viable option.
  • If the detector is unusable and none of the above actions resolves the issue, as a last resort, you can disable laser detection in settings. Be aware, this will leave you vulnerable to a laser ticket.  In cases of strong RF driven false alerts, the detector could still alert even with the sensor "turned off".  This is due to a strong interference source and cannot be resolved.
