Re: Laser is always going off. more so when it rains

Mine had a similar problem. Except it was Ka going off almost constantly. Luckily I was able to fix it, maybe it will work with laser constantly going off.

1. Disassemble the unit (there are 3 screws on the bottom)
2. The plastic casing will be free now to be pulled off.
3. Now you have the complete circuit board, you want to remove the metal channel casing that covers the rear part of the board. I believe there were 5 or so screw on the bottom you will need to get with a precision screw driver.
4. Once the metal cover is removed clean everything thoroughly with a q-tip. In my case the gold plated channel the metal case covered has some spots that were dirty and once that was clean I haven't had any other problems.

I have a Rocky Mountain KAT-TRAXX Radar.laser. g-force, it will not go go to Radar detector mode when I turn it on or when I try to select Radar mode. This option is gone

Lol fake so you are telling me that whenmine detects cops from miles away its lying even though I see them. Read the description *******! He had the Kat Traxx. That unit does not have a radar scrambler or claim it does. It has a laser scrambler which by the way are still active scramblers and laser scramblers are still legal. As for your problem, call Rocky mountain radar they are helpful and will talk to you to try and fix it if not you can send it in to them and they fix it for you.

Police pointed laser at me on freeway and 7100 did not detect

the laser receiver on these are really horrible it usually only picks up the laser if its fired directly near the unit but most cops fire the laser at the front grill or rear of the back of the car and the model you are using is a low end model so the field of view for picking up the laser is really small. most rader/laser detectors that are dash mounted dont usually pick up the laser signal. and when they do its usually as soon as you pass the source of the laser

I also have a 8500 passport that flashes laser and will go off

Does this happen in the city or does it happen when you are out in the middle of nowhere? I have seen laser detectors that are falsely triggered by various lighting devices that contain wavelengths of light similar to those used in police laser.

If this is annoying and you dont want to hear it, you can locate the receiver element that detects the laser signal and cover it up with a piece of black electrical tape. That should stop whatever is causing your problem unless there is something actually broken inside the unit.

Getting false alarm from laser. Laser alarm keeps

If the laser continuously falses even with the car's ignition turned off, then your radar detector has an internal electronics problem. If your radar detector frequently or nearly continuously falses for laser while you are driving even in the middle of nowhere, then most likely the cause of the problem is either poor power and ground connections or electrical noise within your vehicle's electrical system.

Whistler XCS-800 laser falsing

Have you tried it in another vehicle to see if it still alarms? The windshield pitting will not have any effect on the unit. After you test it in another vehicle contact Whistler at 800-531-0004.

Laser warning - Multiple false alerts

Although the detector could have internal problems, it is possible that it is coming from a real source.
A route I took between home and business triggered mine along the same stretch every time I passed it and after looking a a map and comparing it with the stretch I drove, I found that the Marine airbase at Miramar California was visible (line-of-sight) between two mountains only along that stretch.

Note if the falsing happens at about the same point each time.
I just learned to ignore the laser alarm if it triggered during that 1-2 mile 'window.'

False laser alerts

Bel has a firmware fix to solve these issues. It if free if your RD still is in warranty. Of course, covering the rear laser sensor may solve the problem. That isn't a really bad idea since the rear laser sensor on all radar detectors is pretty much useless anyway.

False Laser warning when engine RPM goes over 3000.

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 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...
