    OPERATION Field Disturbance Sensor Rejection (FDSR) Traffic Flow Sensor Rejection (TFSR) Recently many new products that operate on police radar frequencies have been causing nuisance alerts to radar detectors. These radar based sensors are installed alongside the Highway and more recently on vehicles used as lane change assist / blind spot detectors / collision avoidance systems.
  • Page 16: Ka Narrow Mode

    OPERATION Ka Narrow Mode Many countries do not share the same Ka radar guns as the USA. Having a radar detector that scans the complete Ka band may not be necessary if your Country is only using one or more of the following (34.0 or 34.3 GHz). See Option Select Mode to engage Ka Narrow mode.

  • Page 25: Speed Monitoring Technologies

    SPEED MONITORING TECHNOLOGIES ARE DETECTORS LEGAL? Check with your country’s laws regarding radar detector ownership and use. Check for loose lighter socket; tighten and clean. It is the responsibility of the individual radar detector user to know and understand the laws in your area regarding the legality of the use of radar detectors.
  • Page 26: Laser Tips

    For best protection, keep these points in mind: • Because the vehicle’s license plate or headlights are the laser gun’s primary targets, mounting the Whistler detector on the dashboard can improve laser detection at short range. • Do not follow closely behind any vehicle you cannot see through.
  • Page 27: Other Speed Detection Systems

    SPEED MONITORING TECHNOLOGIES This laser/radar detector receives signals from traffic radar guns at X Band (10.500 - 10.550 GHz), K Band (24.050 - 24.250 GHz), and Ka Band (33.400 - 36.000 GHz). NOTE: Your radar detector is designed to alarm if an officer is transmitting on any one of the above radar bands.
  • Page 28 SPEED MONITORING TECHNOLOGIES NOTE: The latest tool Police have to detect radar detectors is called Spectre. Spectre can detect the majority of undetectable (VG-2) laser/radar detectors on the market. It is the responsibility of the individual radar detector user to know and understand the laws in your area regarding the legality of the use of radar detectors.
