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 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 four-LED display will illuminate in a distinct pattern. This illumination pattern occurs rapidly and is coupled with the distinct Laser audio alert. 16 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 flashing 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 confirms Highway Construction/Maintenance ahead LED # 2 confirms Highway Hazard Zone Advisory which could indicate an accident ahead LED # 3 confirms Weather Related Hazards such as fog ahead LED # 4 confirms 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. 17
