X, K, and Ka Superwide are the radar bands that are used by police radar guns. X band was the first band used for by radar guns, but is now the least used. All radar detectors that we carry detect all 3 of these bands.

The display just shows you the different types of radar bands it is detecting. For example, the is an X band, a K band, a KA band and so forth. All it is, is a different frequency of radar being used.

My radar detector goes off everytime i accelerate. can i fix it or is it broke?


by going off do you mean alerting you or is the power turning off if it is alerting you you may have electronic interference in the car if the power is going off it may be as simple as a short in the power cord
cobra 773-889-3087 sells then for 10.00 or you can trade your old detector to them and get the next highest model at a discounted price

What is pop and spector mean


POP is a type of radar mode which only a couple of radar guns have. In essence, radar gun in POP mode emits an extremely brief signal to measure a car's speed. This brief signal lasts for less than 1/5 of a second. POP mode can not legally be used to write speeding tickets since it is not as accurate as the radar gun's normal operating modes, and since POP mode provides absolutely no radar tracking history.

Most people turn off POP mode in their radar detector's options since POP radar is very rarely encountered and since users experience excessive false alerts with POP turned on.

Spectre refers to the Spectre radar detector detector (RDD) which police use to locate drivers who are using radar detectors. The current Spectre models in use by law enforcement are the Spectre III and IV models. Some Cobra radar detectors claim to be able to detect the Spectre I. This is of no value since all Spectre I RDDs have been upgraded to later Spectre models which Cobra radar detectors can not detect. In short, turn Spectre detection off since this feature is a needless source of false alerts.

Cobra XRS 9440 will not detect police radar. Does not alert when I drive by a police car. How can I fix this problem? Is there a way to change the settings so that I can be alerted when there is police...


Radar detectors are not police detectors. Radar detectors only alert to police when the police have their radar guns turned on. Most police officers operate their radar guns in "instant-on" mode rather than leaving their radar guns turned on continuously. Instant-on operation involves very briefly turning the radar gun on for up to a second or two in order to get a vehicle's speed.

Cobra radar detectors are known to have great difficulty detecting the 35.5 Ka band radar gun frequency. This should be considered a serious problem since 35.5 Ka is the second most popular Ka radar gun frequency following the most commonly encountered 34.7 Ka radar gun frequency. There isn't much that Cobra can do about this issue since their competitors hold all of the really good patented solutions for detecting 35.5 Ka police radar while ignoring false alerts caused on this frequency due to other radar detectors.

Undersatanding the 12 bands of cobra xrs 797


Its all marketing hype. Cobra breaks up the three X, K and Ka bands into sub-bands, and they do the same for the single 904nm laser wavelength. There are no sub-bands for X or K band. In the USA, Ka band radar guns operate on three Ka band frequencies: 33.8, 34.7 nd 35.5 MHz. Cobra also breaks up the single laser band based on the known pulse rates of various laser gun models. Yet in general if you get a laser alert from a nearby cop then likely you have been tagged and will be getting a ticket.

Cobra xrs757 X Band


The x-band is the considered a "trash band". It picks up things like automatic doors at supermarkets and such. About every radar detector made has an X band for non-police radar. There is no way to turn this band off on the XRS-757.

Holding down the dim button for 2 seconds turns the V alert on/off
Holding down the city button for 2 seconds turns the Spectra on/off
Holding both city and dim together for 2 seconds turns K and Ku band on/off.

I have a cobra radar dector esd 737 and i sdoesnt pick up cops tell they are like not even a half a mile ahead of you and tips or ideas how to get it to work better


Detecting of radar or lidar emissions depends on mounting of detector.In My experience it is best to mount it just above windscreen wipers.You must check if your detector is visible from license plate level. This is important for laser detection. For other measuring devices it's only important to be visible.Higher mounting facing downwards will reduce false X and K/Ka signals.It will reduce detecing of true as well, so it is all up to you.You must know that laser detecting only covers your car.It d'ont matter if a cop is 300m or 1800m away.X band has a large emission, and it is easily detected.K/Ka band is a pulse emitting and has a lot narrow detecting point.It is effective at max 800m.In ether case speed can be reduced 20-30 km/h in city, and 30-50 km/h on highway.

Radar codes


VG-2 is a technology that police use to detect radar detectors. Detectors with this feature will detect when VG-2 is in use, and alert you to its presence.

X, K, and Ka Superwide are the radar bands that are used by police radar guns. X band was the first band used for by radar guns, but is now the least used. All radar detectors that we carry detect all 3 of these bands.
