Question about Escort Passport 8500 Radar Detector
Every time my engine rev's over 3000 rpm, I get a false laser warning. As the rpm drops below 3000, the alarm goes away. The car is 1.5 years old and this is a problem that has showed up only now after working fine for over a year.
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.

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.

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.

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

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.

Deadcandance's - YOUR THE BEST. 3 years of this **** and took your advise with the q-tip....works like new. I cant thank you enough.

Good news - I fixed it myself for free by removing three screws! It does NOT require re-calibrating, new capacitors, or sacrificing LASER detection capacity. All you have to do is follow the solution #3 as of now) posted above - it's that simple! It was posted by deadcandance

I tried the q-tip solution and was tempted to use rubbing alcohol to really clean the unit but held off and to my surprise it worked. Travel 80 miles a day and have had no false alarms in over two weeks.

Deadcandance, you are the man. This solution worked great. I first tried contacting Escort, the customer service guy was very short with me and told me it's $59.95 to send back the unit (out of warrenty) for repair. I just took apart the unit, removed the circuit board chassis, wiped it down with a Qtip, blew out the horn, reassembled and retested it. It works fine, problem solved ! Thank you again deadcandance.

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
