Traffic or no traffic when the sun gets low in
late afternoon my RX65 Pro gives constant false laser alerts. Seems
like once it is set off it does not stop! Very
annoying, not worth using when it starts if on a west bound route! I
remove it from the windshield and put in the seat beside me and hope I
get radar bounce. This is no good for laser of course. Going to try and
mount further back in shade?

Re: 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.

Laser is very sensitive to false alarms often set off when driving by an airport, or military base. Set your laser on City Mode and pay attention exactly where it goes off. Mine goes off constantly in the same place which is a air force base in Tucson, AZ. Unless you drive like crazy shut it off in the city although the cops like to use a hand held one in school zones. In 6 years of driving in Arizona I have had one real laser alert, and other than false alerts, real ones are far and few in between. Check when and where the unit alerts and use different sensitivity settings. One more thing, if your laser warning goes off you already have the ticket since the cops use them at close range unlike the radar bands. Hope this helps.
It could be picking up garage door openers, which are a common false alert for radar detectors. In a neighborhood, there are all sorts of sensors that give off false alarms. I usually turn mine off when driving through a neighborhood as police are less likely to be using radar (unless in a school zone).
This detector - along with other high-end types that require a microprocessor to analyze signals - performs a self-test when powering up. This is done for the same reasons a Power On Self Test is done on your computer. There's a lot going on inside and if just one area is malfunctioning data may not be processed correctly and in the case of the detector - resulting in aggravating false alarms or worse - not indicating an alert when needed.
You should arrange for the detector's return to Beltronics for thorough checking / realignment. Contact Beltronics via this link.
how long have you had it? Have you had a radar detector before this one? Try a factory reset - hold in the power button and the quiet button, while holding in these buttons plug in the power cord. The unit will beep twice indicating that its reset. Remember the unit is not a "Cop" detector its a radar detector so not all police cars have radar in them and if they do they may not have it turned on.
This is fixable as described in other threads here. This is annoying and seems to be random, though it also does it sometimes when the wipers are turned on or I use the windshield sprayer. 2 minutes with a smal Philips screw driver and a Q-tip will fix it. I just did mine and it works great now.
Unscrew the three screws, pop the three components apart (it really is a no-brainer since they only fit back together ONE WAY, so don't be nervous. There is not anything that is going to fall apart or spring into a hundred pieces in there.
I used canned air to blow everything out and just used the Q-tip on the front window and the parts that looked like the detector window internally... I didn't bother swabbing all of the board.
IT WORKS! GREAT FIX!!!!! DO IT!! NO MORE FALSE LASER ALARM WHILE ACCELERATING and randomly.
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.'
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.
