  • Page 17: Setting Saver

    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 18: Laser Signature Id (Lsid)

    OPERATION Laser Signature ID (LSID) Identify the Laser gun’s pulse rate or PPS (Pulses per Second) that is transmitted by the speed laser gun. LSID may also be used to identify other forms of laser sources such as LACC (Laser Assisted Cruise Control) systems found in some high end vehicles.
  • Page 19 OPERATION The L c segment is an area known to have laser falsing from some new vehicles with Laser Assisted Cruise Control (LACC). This segment is defaulted to off. If vehicles in your country do not have LACC systems, you may turn on this segment in Option Select Mode.

  • Page 28: Laser Tips

    SPEED MONITORING TECHNOLOGIES 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 29: Other Speed Detection Systems

    SPEED MONITORING TECHNOLOGIES Radar Facts - Continued 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 30 SPEED MONITORING TECHNOLOGIES Radar Detector Detectors: VG-2, Spectre - Continued vulnerable to receive two tickets; one potential for speeding, and the other for possession of a detector. 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.
