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 transmitted
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.
