When a radar or laser is detected, the unit will make noise. As you get closer to the source of the radar or laser, the noise will get louder and the signal levels (if you have a detector that shows signal level) will get stronger.
Since police officers like to wait until you are close to them, they may keep their radar guns turned off until you are very close to them. Once they turn it on, you are likely to be busted unless you can REALLY slow down quickly. Most radar guns take a series of average measurements on the speeding car. If the samples are too far apart, it keeps looking for a series of successive speeds that are close. This happens in a few tenths of a second.
SO even if you hear a SLIGHT noise from your detector, it may have been from a brief instant on radar gun in front of you, so BEWARE until you are sure that there is no threat.

The valentine detectors use multiple antennas to tell you where the signal is coming from. This is handy.

SOURCE: Cobra radar detector speaker replacement

I contacted Cobra via internet site and ordered the speaker. However, it has been on order for over 6 weeks and still not here. I would have figured this would be a relatively high failure item and would be stocked. Thanks for the response. ohmhead

SOURCE: My radar detector says selfcalc when it turns on a...

I have the same problem. I chatted with Bel and here's the transcript, FYI:


chatinfo.gifWelcometo Beltronics.! An online representative will be with you shortly. Youare number 1 in the queue. Your wait time will be approximately 1 and 9seconds. Thank you for waiting.
chatinfo.gifYou are now chatting with 'Brian'
Brian: Welcome to Beltronics Live Chat. How may I assist you today?
you: Hi Brian, I
you: own a Bel pro rx65
you: and it gave an error
you: that said
you: selfcal4
you: or something like that
you: then it said service
you: required
you: what does this mean?
Brian: Thereare a number of things that may cause this ERROR message. Please besure that you are getting consistent voltage (does the lighter socketstay ON all the time? Does it do the same thing in other vehicles?). If the display reads "Service Required" not caused by the above, itmeans it has failed it's self-calibration and requires service. Pleasecall our Customer Service Department at 800-341-2288 and they will giveyou a repair authorization number and instructions on how to return itto us so we can take a look at your detector.
you: Oh i see. what's the cost for repair?
Brian: That is a $59.95 repair fee. To set that up, please call Customer Service at 800-964-3138, option 2.
you: and what cause calibration to fail?
Brian: If the reasons listed above don't sound like what's happening, then it would be up to a repair tech to figure out why.
you: I had left it in the car in hot weather. would this be a cause?
Brian: It's possible, over a long time in the heat to develop.
you: I can call either number correct?
Brian: Correct.
you: ok thanks

I called the number and they were helpful, told me to use a packing service like UPS and such. Insure it. And it would take about 5-7 days for them to work on it, another 3-4 days of shipping time.
Considering the reviews on the rx65 and the prices for detectors out there, and considering that they will also apply any software updates (bought mine in '06) the $60 repair fee is worth it for me.

False alarm on the laser and stay on very long moment


Many vehicles have built in signals that radar detectors see as a laser radar. Basically there is no way around it. On my vehicles that emit this signal, I just disabled laser detection on the radar detector.

If your radar detector detects laser you are pretty much effed anyway. The time in capturing a speed reading is less than half a second with laser.

My valentine one will not pick up speed camera vans now it was working on KA band then went to K band now will not pick up?


They are using instant-on radar that has a weak K-band signal that is used to turn on the radar when you are in range. The signal is so weak that you cant detect it until you are in range of the main radar set. This is also known as radar detector countermeasures. Laser is worse. I have beaten laser twice with my Valentine 1 in California where it requires 2 reads to nail you. Slam on the brakes when your detector 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.

Reading the radar detector


These are just the frequency ranges, or "bands" that your detector is detecting the frequencies...

X, K, Ka (Kappa-Alpha) are different bands of frequencies.

Ku is a band of radar used in some places by law enforcement. It is not used everywhere and can be a pain if it goes off for no reason. I recommend consulting your manual and turning the Ku band off if it is not used in the area in which you live. This will enable your detector to become more reliable for when you are being "zapped" by law enforcement

Pop is a way of using radar where the officer turns his radar on and off quickly. As a car approaches, they will turn the radar on long enough to get a speed reading, then immediately turn it back off to avoid detection by civilian radar devices. Some of the newer models of radar detectors have a feature which detects pop radar.

Every electronic device emits a frequency. Vg2 is what law enforcement use in states where radar detectors are illegal to identify whether a car is using a radar detector. The newer version of vg2 is called spectre and accomplishes the same thing. Some radar detectors can pick up on vg2 and spectre so the owner can turn the detector off before they are detected by law enforcement.
