5. Instant-on/Pulsed
Radar
If you are the target vehicle, an alert caused by
instant-on or pulsed Radar will be strong and
immediate. When encountered, your unit responds
with a three-second audio/visual warning.
Typical False Alert (Radar)
Ideally, a Radar detector should only alert in the
presence of police Radar. However, because other
devices share X and K bands 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 identifi ed (supermarket, bank,
commercial building etc.), caution is advised until the
source can be confi rmed. 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 four-LED display will
illuminate in a distinct pattern. This illumination
pattern occurs rapidly and is coupled with the 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
stability of the Laser gun and the fact that it is
impossible 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
received from your unit should be taken seriously.
Safety Warning System (SWS) Alerts
With the Safety Warning System feature ON and an
SWS transmitter in use, your detector will provide a
unique, three-second, two-tone “beep” followed by
clicking, coupled with the fl ashing of the (S) LED and
the appropriate LED in the four-LED display. To select
SWS ON or OFF, see Selectable Features, page 9.
LED #1 confi rms Highway Construction/Maintenance ahead
LED # 2 confi rms Highway Hazard Zone Advisory which
could indicate an accident ahead
LED # 3 confi rms Weather Related Hazards such as fog
ahead
LED # 4 confi rms Emergency/Slow Moving Vehicles in transit
When only the SWS audio warning is provided, the
category referenced is Travel/Convenience.
Information or the category is unknown.
