Whistler 1783 detector shuts as soon as it goes thru start up mode. seems to get very hot to touch.

Try the factory reset - hold in the power and quiet buttons, while holding in these buttons plug in the power cord. Unit should beep twice. The unit will get warm to the touch.

I turn it on everything is fine it goes threw its start up self test mode seems fine, then in about 25 to 45 seconds it goes off like its detecting a signal at full strength. one time it will be x band....

Does it alarm like this in another vehicle? Does it start this after you press a button to change a feature? The unit does have an auto off function that turns it off and it also has a "teach mode" that goes through all the alerts. This is why i asked if the unit starts this after you press a button as these two features can be engaged if you hold a button too long.

Got a whistler xrt-695 from individual. unit powers up goes thru all the frequencie alerts and laser alerts, scans menu to tell what is active. Seems to be perfect. x-band is on, K,Ka, Laser, all of it,...

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.

When I accelerate from either a dead stop or if I increase my speed as I'm driving, my lazar alert goes off when there's no threat.

Scroll down a few posts and a guy "blokhead" posts the solution to the "laser" problem. And then another posts some pictures. I only took out the first 3 screws, opened it up, pulled the circuit board out, and then used a tiny screwdriver to seal up the gaps around the metal box around the laser sensors. I also tightened up some of the tabs that hold the box to the board. It definitely had some little gaps that had opened up over time causing RF interference. The guy says if he ever fixes it again he may use some foil tape to completely seal it, I might do the same, but it appears to have fixed the laser issue when you press the gas, and an issue with my keyless remote lock. It would laser everytime I left it on and locked/unlocked the car.

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.

Escort 8500 radar detector

Service Required means that your 8500 has repeatedly failed while attempting to calibrate its radar antenna. This can be fixed by Escort for free if your RD still is in warranty. There is a service fee if your RD is out of warranty, but at least Escort will fully test everything in addition to repairing your 8500, and they will upgrade your 8500's firmware to whatever their latest and greatest firmware is which may help to improve sensitivity, reduce false alerts, or to detect newer laser gun models.

Laser warning going off all the time

Hi All,
I fixed my Radar, No Manufacturer help, no cost to me at all. I got advice from a forum member on a satellite forum I belong to. So what I did was I took apart the radar. Watch carefully how it comes apart so you can reassemble again after. Get a Dry Q-tip (ear swab) leave it dry so you do not end up leaving and residue on the diodes etc. Start by cleaning the horn, wipe the electronic board all over gently with the Qtip , blow ou the diffusion screen (leave the spit in your mouth). After all that I did not see a spec of dirt on the Q tip I used..there was no sign of dirt, residue but whatever I did do fixed the problem. I have been using it for three months and not one false alarm from the laser mode.

Good luck all......

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...
