Performance Verification Conditions that Affect Radar Alerts If you feel your unit is not alerting properly, keep in mind that there are many conditions that influence the intensity or duration of an alert: 1. The police are using instant-on/pulsed Radar, in which case no signal is transmitted until visual contact has been made with your vehicle. For detection of this signal, you must rely on reflected signals from Radar directed at traffic traveling ahead of you. 2. The police Radar unit is positioned perpendicular to the road, around a curve, or just over the crest of a hill, thus, significantly reducing the reception range. 3. The highway traffic between your vehicle and the police Radar source is heavy, blocking or reflecting transmitted signals. The presence of several large trucks between you and the police Radar unit could also significantly reduce reception. 4. Rain or humid weather conditions can absorb transmitted signals before they reach your vehicle, again reducing detection range. 5. The police Radar unit is not properly tuned and is transmitting outside allocated X, K or Super Wideband Ka frequency ranges. Conditions that Affect Laser Alerts If you feel your unit is not properly alerting to the presence of Laser signals, keep in mind that rain, fog, high humidity and other weather conditions can affect the range that the Laser beam can be detected. 18 Troubleshooting Solutions for Common Problems If your unit is not operating properly, please refer to the outline below.
