Question about XRS 9540 Radar Detector

Open Question

Burned Cobra 9540

My Cobra 9540 detector stopped working and unfortunately it was purely my fault. I bought a hard-wire kit, wired it up, and it worked fine. Well one day I changed the location of the detector, thus moving the wire. When I plugged it back in and turned it on, I discovered that I reversed the polarity of the plug (It was a universal hard-wire kit with changeable plugs). It smoked, I was pissed. Oops. Any chance it's fixable?

I hard wired the xrs radar but didnt install the fuse, got it shorted out and now it wont turn on...is there a fix to replaced whatever i burned up?


check for power on the line you may have popped that fuse if fuse ok than you more than likely burnt up most of the electronics in your detector

Can you show me where to get the user manual for a cobra superwide laser detector with model number r-213


Unfortunately, Cobra does not provide secondary or tertiary manuals on their website for this old model of Laser Detector.

Your best bet would be to either purchase a new Laser/Radar detector from Cobra and get the manual from that.

Hope this helps.

Thanks!

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.

I dont understand


That may be because he does not have his radar unit activated. Radar units work by sending out a microwave signal. It bounces off your car and back to the unit. It then calculates the whole distance over time thing and figures out your speed...it's more complicated than that, but I don't feel like giving a class...and I'm not a real genius anyway when it comes to physics and whatever other -ics are involved with the science of radar. Point is...radar units have a hold function..kinda like turning that microwave beam on and off...when the officer has the radar on "hold" there is no beam coming out..which means, there is nothing for your radar detector to detect. When he takes it off hold to clock your speed, the magic beam shoots out, bounces off your car, and returns to the unit..then tells the officer your speed...by the time your radar detector actually lets you know you're being clocked, Mr. Officer is already turning around to come pull you over. Hence the reason radar detectors are a waste of money...but then again, there are plenty of cops that ride around with the the sending out a signal all day and never actually put it on hold...if a cop is using the radar properly, the radar detector in your car will not help you...but, not everyone does what they are supposed to do, so therefore, it may save you from one or two tickets.
Now, the reason it doesn't alert you when the police are right in front of you is because either the police in front of you; A)do not have a radar, B)do not have their radar on, C)they have it on "hold" and are not transmitting a signal, or D)your radar detector is broken and you need to get it fixed or replaced.

Radar detector speaker busted


The best way is to call up cobra or ask them a question through their site.

http://www.cobra.com/index.cfm?fuseaction=support.ask

This will link you to the ask page. Just ask if they will sell you a replacement speaker for the radar detector xrs 747. I just ordered one for a friend and it was $4.32 and $2.50 for shipping.
