Hold all THREE buttons, one is located on the front right of the detector, while turning the detector on.

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.

"Goes off" as in shuts off or provides an audible / visual radar alert?

Are you connected to the cigar lighter / battery; or a wire you believe to be 13.8VDC? Check the voltage of the wire you are using to power the 8500 with a VOLTMETER. You may be connecting the data bus wire in the vehicle instead of a 13.8VDC source. Move the wire to a 13.8VDC source.

You may have received a laser hit or a qucik shot on the radar. We don't normally keep the radar on constant - a click of the button sometimes real fast will grab your speed, lock on the display and then the signal will cease to omit.
You may also want to check to see if you are set on city of highway.

Follow the direction of the radar detector. Usually you push the button sequence for calibrate and you drive the car in two circles so it can calibrate the compass.

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......

Hi, I would just write a polite email to the manufacturer and say you have miss placed it while changing vehicles and stress how much you miss the use of there invaluable product.

(this can work to get it free or a bit cheaper)
