Try checking your setting>alert> and make sure all your settings are in the right order. i usually leave it on X+K and leave the Ku Band off since its european and not yet in California. Leave the K bands on and check it out after that. If it still does not work, then if you have a GPS or any other type of strong wireless intereferences then it will greatly reduce the signal distance. Mid-Windshield is the best place to mount the radar since the Laser detector needs a full 360' view and have a clear path looking ahead and through the back seats to the back.

What does K1 mean?


The letters X, K, and Ka designate radar frequency bands used by radar based speed monitors. The letters correspond to designations given by Federal Communication Comission (FCC) frequency bands reserved for speed monitor equipment.
  • X band - 10.525 GHz
  • K band - 24.150 GHz
  • Ka band - 33.4 ... 36 GHz
The number (range is 1 ... 5) is the radar signal strength, where 1 indicates weakest signal (you are still at some distance, or maybe false alarm) while at 5 you should be able to see the white in the eye of the cop holding the radar gun.

The letter V indicates the detection of a "Detector Detector". Devices like the Cobra are illegal in some countries and police has counter-measures available to detect some radar detectors. The maker of the Cobra states, their products go unnoticed but that won't help you if highway patrol sees the thing sticking on your windshield.

The letter S indicates hazard warnings (like train crossings).

Finally, L indicates detection of a LASER based velocity detector.

How does it work


Radar detectors are similar to radio receivers that are in your car or home. Radio receivers pick up signals in AM and FM frequencies. Radar detectors find the frequencies that are used by police officials using radar guns. Once the radar detector finds a frequency being directed at your car, it signals the driver somehow, most likely by beeping. It is a simple technology. Although, as law enforcement agencies expand the frequencies to detect speed, companies need to produce more radar detectors

NOT PICKING UP SIGNALS


Radars are like just about anything else you buy these days, you get what you pay for. If you want a cheap but most reliable for the price I would suggest the Whistler XTR-695 *est. price 150 bucks. Although many detectors are prone to being detected by radar detectors (used by law enforcement) this one is a little more likely. So if your state has a ban on radars I wouldnt buy. As far as distance in signal pick up the Valentine One I would go with *est.price400 bucks.

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.

Pramming for cobra xrs 9330 radar detector


Here is a link to Cobra's RD product manuals page:

Cobra - Product Manuals

To the original poster, the officer could have used laser, vascar, or pacing to issue a speeding ticket. The officer also could have used a very quick burst of instant-on radar which Cobra brand radar detectors are notorious for not detecting. The officer also could have used a 35.5 Ka band radar gun. Cobra and other import brands of radar detectors usually have great difficulty detecting 35.5 Ka band radar.

Cobra 757 codes


X stands for wide band radars(easy to detect,lots of false alarms)
K/Ka stands for pulse band radars(similar signal has auto doors)
W,L stands for laser detection (very little false signals)
Ku stands for signal most used on speed cameras
V stands for radar detectors detector
Have in mind that you can only lower your speed 20-30 km/h in city zones, and up to 50 km/h on highway.This depends on car,brakes and You.

Troubleshoot


You should try to find out what type of radar devices your police uses.ESD7000 model does not support some devices such as Ku band radar signal, but it should detect all laser signal.Laser signal is often jammed by sun light.If your police uses radar detector detectors VG2 it will force your detector to hide from it making it invisible for detecting.Try talking to someone who has other type of detector that works in your town.It is possible that you will be forced to buy another model.
