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. This blocks/reflects
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 trans-
mitted signals before they reach your vehicle, again
reducing detection range.
5. The police Radar unit is not properly tuned and is
transmitting outside the fcc 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 traffic conditions can affect the
range that the Laser beam can be detected.
