NOT PICKING UP SIGNALS

I haVE A COBRA XRS 9440 AND IT IS NOT PICKING UP RADAR. I HAD A MOTORCYCLE COP POINTING HIS RADAR AT ME AT ABOUT 30 FEET AND IT STILL DIDN'T PICK HIM UP. I HAVE HAD SEVERAL TIMES IT HASN'T PICKED UP ANY RADAR SIGNALS. WHEN IT HAS I HAVE BEEN RIGHT ON TOP OF POLICE WITH NO TIME TO REACT. I KNOW I WOULDN'T BUY ANOTHER ONE AND AM WONDERING IF THERE ARE ANY THAT ARE RELIABLE.

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.

Why does a 8 appear upon start up on the screen?


That number is the signal strength indication. IF you get four beeps when that shows up and it could be E instead of 8, the unit has detected something wrong.

I rerouted the power for my Cobra XRS 9440 and I accidently reversed the polarity of the power cable when I plugged it in. It fried the detector... I'm pretty handy with circuits and soldering, I'm hoping...


Did you first check the fuse in the units power cord? The fuse should be in the part of the power cord that plugs into the lighter socket. A 2 amp fuse should be good enough.

These don't detect like advertised


The detector will only work if there is a signal transmitting at the time. Depeding on what country you are in, police usually don't activate their radars three minuites before they register your speed. These are more meant for stationary speed cameras than hand-held ones.

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.

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.
