Q. Are radar detectors legal?
A. Radar detector usage is legal for non-commercial vehicles in 49 states. (Please be aware that Virginia and Washington D.C. ban the use of radar detectors, as do some provinces in Canada.) Radar detectors are outlawed for use by commercial vehicles in all states. It is also illegal to use a radar detector on any military base or military installation.
Q. What’s the difference between a portable and remote radar detector?
A. Radar detectors are available in two distinctly different platforms... portable and remote. Portable units mount on your front windshield and are powered by a cigarette lighter/power outlet. They offer very good performance and are capable of being transferred to other vehicles. Remote units feature a front and/or rear externally mounted receiver for exceptional performance along with internally mounted audio and visual warnings. These are custom installed and blend in naturally with the vehicle interior.
Q. Why should I select a K40 Remote System?
A. If you own a luxury or performance automobile, you have invested in a fine piece of machinery that reflects your discriminating tastes. You want to maintain the visual integrity of the driving environment and keep distractions to a minimum. Thus, your expectations will simply not be met by a one-size-fits-all traditional dash unit or other brand remote system. Plus, with the K40 Consult each K40 remote system can be custom designed for the individual drivers needs and vehicle's specific make and body style.
Q. How does the wireless remote control work?
A. Only K40’s Remote Radar Detectors are controlled with a hand-held remote control. Select a variety of modes with a single click, including: On/Off, City/Highway, Voice/Tone and Volume/Mute. Then put your Remote Control away until you want to change preferences.
Q. How much warning time does a K40 radar detector provide?
A. Trying to estimate warning time in an actual mile or feet measurement is impossible because 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.
Q. What's the difference between sensitivity and selectivity?
A. Sensitivity refers to a radar detectors ability to pick up police signals at the greatest distance. Selectivity refers to the detectors ability to filter out signals that are not true police signals, but 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.
Q. Sometimes I pass a parked police car or one traveling in the other direction, but my detector doesn't alarm. Why is that?
A. 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 anything 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 the vehicle's speed. K40 radar detectors are sensitive enough to detect these brief, weak signals, but you have to pay attention and react quickly.
Q. I drove past a speed box and it displayed my speed. How and Why?
A. 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.
Q. I drove passed a speed box and my radar detector didn't go off. Why?
A. 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" out of calibrations 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.
Q. What is “POP” Mode?
A. 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 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.
Q. Do you “jam” radar?
A. No. 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.
Q. Can a tinted windshield negatively affect the performance of my radar detector?
A. Today, many high-end car manufacturers like Mercedes 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 that 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, or 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.
Q. I've heard that you pay speeding tickets...is that for real?
A. Because we have absolute confidence in the performance of our products, you should never get a 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 tickets issued in school zones, construction zones and/or when DWI or DUI is involved). No questions asked.
Q. What is LIDAR?
A. LIDAR stands for “light detection and ranging.” Using the same principle as RADAR, a LIDAR instrument transmits light at an object, the object reflects the light, and the instrument analyzes the speed of the reflection. Through this analysis, the location and movement of the object can be determined. The Defuser g5 is an effective device against FDA licensed laser guns.
Q. How does the K40 Laser Defuser g5 work?
A. The Laser Defuser g5 is an active protection system that detects and deactivates police laser signals. The Defuser is designed to receive a laser light signal transmitted by police laser at 904 nanometers. It then notifies the driver with a unique audible and visual alert hidden discreetly inside the cars cockpit. Simultaneously, the Defuser sends out a return pulse signal at the same frequency as police laser that the laser gun cannot understand. The purpose of any laser jamming device is to give the driver time to slow down in the event that they are exceeding the posted speed limit.
Q. Why do people need the K40 Laser Defuser g5 if their current detector has laser detection capabilities?
A. The high tech police laser guns being used today are fast and far more accurate than yesterday's radar. At typical target ranges, a laser beam measures between 18" and 36" in diameter, depending on the gun. And this narrow, infrared, monochromatic, one milliradian, laser emission does not scatter like a police radar signal. In other words, a driver receives no advanced warning to laser when it's aimed at another vehicle. With laser guns capable of measuring a vehicle's speed in less than one second, by the time an ordinary laser detector alarms it's too late. Only the Laser Defuser can provide drivers with the time needed to react and safely reduce their speed every time. Guaranteed.
Q. Can the K40 Laser Defuser g5 be installed on a vehicle that doesn't have a front license plate?
A. The K40 Laser Defuser g5 is designed to work with any make or model of vehicle, with or without the frame. In states that do not require a front license plate, the modular design of the Defuser allows it to be easily removed from its frame and remotely mounted in the front grill or air vent using the Universal Mounting Bracket. Please remember, in order to work effectively, the Defuser must be mounted parallel to the ground with a clear, unobstructed view of the road. The sensor/transmitter should not be mounted facing up, down, to the side, or hidden behind anything . . . including the car's grill or bumper.
Q. If a vehicle is equipped with the K40 Laser Defuser g5 does the driver still need a radar detector?
A. The Laser Defuser is designed to detect and deactivate police laser signals only. As most areas use both radar and laser speed measurement devices, complementing the Defuser with an effective radar detector is important. For complete speeding ticket protection, we recommend the including the Defuser with a K40 Remote Radar System to provide maximum protection to police radar while effectively reducing distractions caused by non-police radar transmitters.
Q. Can the Laser Defuser g5 be installed using the same warning lights and speakers that come with the K40 Remote System?
A. The Laser Defuser has been designed to allow integration with any current K40 Remote Radar Detection System. Integrating the Defuser with this system means you will not have to add an extra warning light or speaker to operate the Defuser.
Q. Is the K40 Laser Defuser g5 legal?
A. The Laser Defuser is designed to boost a signal to 904 nanometers, the frequency used by police laser guns. Because it does not interfere with radio waves or any devices regulated by the Federal Communications Commission (FCC), and no laser diodes are used, the Defuser is completely safe and legal to use. Some states also ban the "use" of laser jammers. These are often a secondary, or "possession of a banned device" infraction. Check with your states statutes for specific information.
