Typical False Alert (Radar)
Ideally, a Radar detector should only alert in the
presence of police Radar. However, because other
devices share X band with police Radar, false alerts
sometimes occur. Generally, a false signal produces
only a short audio and visual alert. Since they are
most often weak, it is possible to drive out of the
signal’s range very quickly and receive only a brief
alert. Although many times the probable source of
the false signal can be identified (supermarket,
bank, commercial building, etc.), caution is advised
until the source can be confirmed. The X band alert
pattern caused by a non-police source can look like
the initial alert produced by actual police Radar. For
this reason appropriate action is required any time
an alert is received.
Laser Alerts

If a vehicle is a long distance from the source of
Laser pulses, fewer pulses will generally be received.
The closer the vehicle is to the source of Laser
pulses, the greater the likelihood of receiving a
steady stream of Laser pulses. The reason for this is
the aiming stability of the Laser gun and the fact
that it is difficult to hold the gun absolutely still.
Any movement of the gun results in motion of the
beam at the target. The further the target, the
greater the displacement of the beam and the
shorter the dwell time of the beam at the target
point. Therefore, there is the possibility of receiving
only a few Laser pulses. Due to these characteristics,
all Laser alerts should be taken seriously.
