False Laser warning when engine RPM goes over 3000.

This is a known fault of this detector. After so much time the laser gets out of alignment and starts to give false readings. I've been searching on this myself and have found many other people complaining about the same thing. I also have my unit hardwired into my car and still have the problem.

The only DIY fix is to use the expert mode and turn off the laser.

The only true fix is to send the unit into passport, pay $60 to have it fixed.

Has any aftermarket electronics been installed recenty? Ie amplifier with sub, or do you have lots of things plugged into you cig lighter? Anyway to solve the problem you can hardwire the detector to your fuse panel on an isolated fuse to get rid of any interference, or you can purchase a device called a ground loop isolater, either way it should solve or at least reduce the problem.

Good Luck

Hey guys, me again....Deadcandance..... I posted my trouble on a Satellite forum I belong to and I had a suggestion which I tried. And it worked!!!!! No manufacture returns, no cost at all, what I did was tokk it apart gently ...watch how everything comes apart so that you can reassemble again....

Start by getting a couple Q-Tips (Ear Swabs).Leave them dry so they won;t leave any residue on the diodes. Gently clean the horn, than clean/wipe the electronics board, and blow out the diffusion screen (leave the spit in your mouth). After I wiped the unit down, I didn't see any dust persay or dirt on the Q-tip but whatever I did, fixed it....
It worked for me. Took 15 minutes to do and I have been using the Radar for three months and not one false alarm in Laser mode.
Good luck...

The cheapest and best thing is to turn the laser band off. Laser band is quite useless due to the fact that if it ever goes off in a true alert situation, your might as well get ready to pull over. It is not like with the K or Ka band where the radar signal is not concentrated and doesn't have to be directly pointed on any one car. The laser beam has to be pointed by a cop to your vehicle to get your speed reading, but that's when (and if) the detector picks it up and it is too late. Therefore, it is as good turned off as it is on. But there are not too many lasers that are in use by the highway patrol. But Escort is great for K or Ka bands, no doubt.

The poster above who states "Laser band is quite useless due to the fact that if it ever goes off in a true alert situation, your might as well get ready to pull over" is incorrect. There is an occasional speed trap in the same place on my way home from work. When the cops are there, they are using laser. I'm never the only car there and my 8500 ALWAYS tells me when they've lasered someone else...everytime. Keep the laser.

I would never run the unit without the laser function on, I have been in several situations where I have gotten laser hits as it was used on other vehicles in front of me. That being said, if your pretty handy with taking things apart and cleaning them, I would try that. My only concern here is that while you have stopped the false alarms, how do you know it is even now working at all? Sending the unit in for repair would be the best approach for a fix in this case, or upgrade to another manufacturers unit. I have both the 8500 and the V-1 and I an on the same V-1 (not considering ugrades) unit for 20 years. One upgrade resulted in a new unit as it added laser and Pop modes, others have been software related

It needs re calibrating... send it back to manufacture
