How much warning time does a K40 radar detector provide?

Trying to estimate warning time in an actual mile or feet measurement is impossible since true warning time is influenced by many outside variables that have nothing to do with the radar detector itself. For example, the strength of the radar signal being transmitted, the direction the gun is pointed, the length of time it is transmitting, the positioning of the patrol car, and the influence of other objects around you may all affect how your radar detector receives a signal. For these reasons, don’t expect your detector to achieve the same warning distance every time you encounter police radar. Just expect it to do what you bought it for: give you enough time to slow down and save yourself from receiving a speeding ticket.

What’s the difference between sensitivity and selectivity?

Sensitivity refers to a radar detector’s ability to pick up police signals at the greatest distance. Selectivity refers to the detector’s ability to filter out signals that are not true police signals, yet operate on the same frequencies as police radar (i.e. security alarms, garage doors, automatic doors, etc.). The filtration software built into K40 radar receivers features very unique microelectronic processors that minimize distractions that come from non-police radar transmitters. This helps give you the time you need to react to real potential threats, without the constant “falsing” that makes other detectors difficult to use in today’s challenging driving environments.

Sometimes I pass a parked police car or one traveling in the other direction, but my detector doesn’t alarm. Why is that?

Radar detectors are essentially superheterodyne radio receivers. Like any radio, they’re passive devices that listen for microwave signals. The main difference is that they are specially-tuned to detect microwave frequencies transmitted by police radar and laser guns.If a police car is not equipped with a radar or laser gun, a radar detector cannot possibly locate it. Also, if no signal is transmitted when you pass the police car, there won’t be any signals for your detector to receive.Police may also use a sinister technique called “Instant-On” or “RF Hold.” During this type of encounter, an officer will wait until a targeted vehicle is within range to send a quick burst of radar to clock its speed. K40 radar detectors are sensitive enough to detect these brief, weak signals, but you have to pay attention and react quickly.

I drove past a speed box and it displayed my speed. How and why?

Speed signs – or speed reading boxes – are radar-based. Radar detectors are not radar jammers. Jamming radar is a federal offense and is prohibited by federal law nationwide. These informational-only speed readers, if working properly, should always detect and display your speed.

I drove past a speed box and my radar detector didn’t go off. Why?

Speed signs – or speed reading boxes – are not used to issue traffic tickets or citations. As a result, these portable systems are not calibrated regularly and can “drift” away from the FCC-authorized frequencies. Because of this, when passing one of these signs that say Your Speed Is…,” you may or may not receive an alert. These devices are primarily placed in residential areas as a reminder to obey the speed limit.

What is “POP” Mode?

POP Mode, when turned on, enables the detection of a special band of radar known as “POP.” This is a very short transmission signal that allows the user of a radar gun to capture a quick read of a vehicle’s speed prior to setting the gun to another band. K40 recommends that you keep the POP Radar Mode turned off for two reasons: 1) POP radar does not transmit long enough to gather information needed to issue a speeding ticket, and 2) keeping POP Mode “on” is known to cause far more false alerts than actual alerts.

Do you “jam” radar?

No, we do not. The sale and use of radar jammers has been banned by the Federal Communications Commission (FCC) since 1997. The fines for each violation can reach up to $11,000.

Can a tinted windshield negatively affect the performance of my radar detector?

Today, many high-end car manufacturers, such as Mercedes-Benz and BMW, are incorporating special tints into their windshields to protect the interior look and comfort of their cars. Unfortunately, this creates a very real problem for people who own portable radar detectors. Putting tint of any kind on your windshield that contains metal film is essentially like putting a blanket over your radar detector. While radar microwave signals can still travel through fiberglass, plastic, and glass, they cannot penetrate metal. Some tints are worse than others, but if it contains metal of any kind, it will reduce the performance of any portable radar detector mounted inside the car.

I’ve heard that you pay speeding tickets… Is that for real?

We have absolute confidence in the performance of our products, and you should never get a speeding ticket when they are operating and used properly. In the rare event you should receive a speeding ticket in the first 12 months of ownership, we’ll pay any and all fines (excludes attorney fees and/or insurance premium increases as well as tickets issued in school zones, construction zones, and/or when DUI or DWI is involved). No questions asked.

Laser Transponders

If you’ve ever seen a police officer parked and outside his vehicle looking at traffic with what looks like a small movie camera or binoculars, you’ve probably just been targeted by LIDAR (Light Detection and Ranging), also known as laser. Police laser guns are short-range (typically 1000 feet) and pinpoint accurate. If the crosshairs of the laser gun are targeted on your vehicle, and you’re speeding, they’ve got you, pull over, game over. Unlike police radar, there are no advance warnings for police laser guns. Your only defense is a good offense with Uniden laser transponders. We know a thing or two about combatting police laser, including the latest variable pulse rate (VPR) guns used today. We build confidence and reliability into our products so you can drive without limits, knowing you’re protected.

Three User-Selectable Transmit Modes

Constant Transmit: (Default Setting) For as long as it’s receiving a police laser gun signal, the transponder will continuously transmit back to the gun. For aggressive drivers in areas where there are no restrictions on the use of laser jammers.
Pulse Transmit: Upon receiving a police laser gun signal, the transponder will transmit an “error” signal back to the gun for up to five seconds. The system will then switch to “Receive Only” mode for 30 seconds. Use this setting if you typically drive in an area with restrictions on the use of laser jammers.
Receive Only: The transponder will only detect police laser. No jamming signal will be emitted. Use this setting if you only wish to be alerted when a police laser gun is targeting you.
