This is caused by electrical noise in your car's electrical system. Specifically, the problem is excessive alternator whine. This can be exacerbated by somewhat corroded contacts in your car's cigarette lighter socket or by a somewhat corroded vehicle wiring connection to the back side of the cigarette lighter socket.

One potential solution is to try a snap-on RF filter which is available at your local Radio Shack. You would snap this filter around the positive 12V wire leading to your car's cigarette lighter socket. Preferably, if there is enough free slack in the 12V wire leading to the cigarette lighter socket, you would wrap this wire through the RF filter twice before snapping the RF filter closed around the wire.

    For all these answers for fixing the laser detectors, I think that one better way to test is the way that I tested. I have a monster power supply and I used an adapter and still had laser going off. There is a reason, and I don't think that it is noise in the electrical system, necessarily.

    I think light is affecting the laser detector, or even possibly bluetooth devices, or something else.

    Desensitizing the laser detector is completely unacceptable and you may as well not even have a detector for laser if you are going to desensitize it.

HOW DO I TURN ON THE AUTO MUTE ON A COBRA ESD 8285

When changing the Settings on your detector, please keep in mind: Each time the unit is turned On the factory settings of Highway and Auto Mute-On will be set. They can be changed while the unit is in use as described in the following sections.
Assistance Muting An Alert
Your detector allows you to quickly turn Off an audio Alert by momentarily pressing the Mute button. If you press the Mute button a second time during the Alert, the audio Alert will be turned back On.
Auto Mute Mode Auto Mute will automatically reduce the audio volume of all alerts after four (4) seconds for as long as the signal is detected. The factory setting for Auto Mute is On.
Highway/City Mode Setting your detector to City mode delays all X band audio alerts at lower signal strength levels. (A single beep will sound when the signal is first Notice detected.) This will reduce false alerts while you are driving in, or near, urban areas where there are many sources for conflicting X band signals such as microwave towers and automatic door openers. To change settings, follow the procedure listed below, which indicates what you will see and hear as you complete each step. The factory setting is Highway mode.
Highway Mode City Mode
Mute Button Press and release
To Turn Auto Mute Off X Ka L S
City Button Press and release
Press and release the Mute button while no alert is occurring.

I have a cobra radar detector model #esd 737 i need a manual went on line cant find any

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!

My radar detector goes off everytime i accelerate. can i fix it or is it broke?

by going off do you mean alerting you or is the power turning off if it is alerting you you may have electronic interference in the car if the power is going off it may be as simple as a short in the power cord
cobra 773-889-3087 sells then for 10.00 or you can trade your old detector to them and get the next highest model at a discounted price

I need to know what the signals on my radar detector mean

The following is a direct link to the PDF owners manual for your ESD 7000:

ESD 7000

Of note, this extremely inexpensive radar detector provides just about the worst performance of any radar detector product currently available from any RD manufacturer. I suggest that you visit radardetector.net to learn more about radar detectors.

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.

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.
