Instant-On/Pulsed Radar
This type of signal appears suddenly when a Radar unit is
“triggered”.The instant-on alert consists of an intense,three
second audio “burst”,coupled with the type of band detected
and flashing of the signal strength bar graph in the display.

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
When Laser is detected,the display will flash “
LASER
coupled with a distinct Laser audio alert.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
stabilityof 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.
