The cobra esd 737 came on when I started the car than went blank, I checked the power card and connection, they all seem to be ok. I need to know if the detector has a fuse in it that could have possibly gone out? The device has always worked very well until now. Please help can't drive without my old buddy. Thanks LMS

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.

I would go to your nearest Radio Shack. Thats where I got mine.

SOURCE: remote does not connect with unit built into car. does not go on

First, the K40 Calibre isn't a terribly good radar/laser defense system no matter what K40 claims. I would rate its radar detection capabilities as fair, and its laser jamming capabilities as poor. But on to your problem. Call K40 and see if they can talk you through any specific procedures which they have. It appears that your Bluetooth remote and the RD are not properly synced. Its best if K40 talks you through the resolution.

Glad to help YOU!

Your COBRA RADAR DETECTOR ESD 737 is VERY-VERY similar to COBRA RADAR DETECTOR ESD 7000.
THIS is yours (ESD 737) and THIS is ESD 7000. As you can see - there's NO DIFFERENCE!

So you can have THIS user manual and there will be no difference!

My best wishes!
