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.
