•360º Force Field™ of Protection
The K40 RL Series Radar Dectection systems, combined with the Defuser EX or EX2, gives you total protection from every kind of police radar and laser used today. From the front, the rear and the sides, the K40 RL series are a virtual Force FieldTM of protection.
•It's invisible! You'll only know it's there when you need it --
Unlike any other radar detection system or portable radar detector on the market, the K40 RL Series are invisible. No plugs, no wires, no unsightly box to compromise the elegance of your automobile's interior, or draw the attention of police or vandals.
•Know where the threat is coming from -- The K40 RL360's patented design includes a concealed system in the front of your automobile, aiming forward, and another concealed system in the rear of your vehicle, aiming behind, giving you twice the protection of any other radar detector on the market. Two LEDs discreetly integrated into your automobile's cockpit alert you of either oncoming or rear approaching radar threats. A voice or tone will notify you of the direction of the threat as well as the band frequency being used. No surprises. You're in control and free to drive without limits.


•Customized for your automobile -- The make, model, interior, accessory package, and even the color of your vehicle will determine its components, programming and installation. Your authorized K40 Dealer is an expert you can trust.
•Customized for the way you drive -- Where do you live? What is your primary driving environment? Urban highways and city streets? Rural roads and low traffic interstates? On the open road, how fast do you typically drive? Who else drives your automobile? The K40 RL Series system features, some of them noted below, can all be programmed and customized for your automobile and the way you drive.
•GPS lets you mark locations where you need an alert -- The K40 RL Series allows you to build your own data base of locations that are important to you, such as dangerous intersections, speed traps, school zones and portable speed cameras. You can Mark to AlertTM or unmark any location with one press of a button.
•Quiet RideTM --The K40 RL Series allows you to set a minimum MPH detection speed that eliminates all audible alerts until the vehicle exceeds that selected speed. It's ideal for long road trips or when you only want to be alerted if you exceed a set speed limit.
•Speed MonitorTM -- This feature gives the driver a constant audible alert whenever a preselected speed is exceeded. The interior LEDs will also illuminate. Great for young or new drivers and accidental lead foot. Self control. Parental control.
