The problem never happens when it's cool or cold
my problem always happens when i turn the unit on, not while already riding/driving out of the blue

i believe the problem might be from the unit getting hot from being in a car, or on a motorcycle, or in a jacket in the hot sun then powering it up while still very hot, some kind of overheat circuit

find a way to cool it off, ride a short distance with it turned off then turn it on or...

also take the 8500 in you right hand and tap it in you left hand 3-5 times, it should start up and be fine. this doesn't have anything to do with temperature but i've had luck with it

good luck

I was travelling through New Mexico at night and the "X band" kept going off every 10 to 30 seconds. This went constantly on for almost 200 miles of travel until I crossed over into Texas then it seemed to...


Actually, in New Mexico and Texas they are using mostly Laser now or XK band that your detector isn't picking up anyway. The way the new systems work they flash on and back off instantly and don't give detectors a chance to detect them. What you are detecting is skip from the increased Microwave signals at night. Not to worry though, they are expecting a new law to be passed that will make it illegal to even have the detector in your vehicle in Texas, the law is expected to go into effect in early Jan.

My radar detector says selfcalc when it turns on and then says service required. Can i fix this my self or have to send it back to get fixed?


I have the same problem. I chatted with Bel and here's the transcript, FYI:


chatinfo.gifWelcometo Beltronics.! An online representative will be with you shortly. Youare number 1 in the queue. Your wait time will be approximately 1 and 9seconds. Thank you for waiting.
chatinfo.gifYou are now chatting with 'Brian'
Brian: Welcome to Beltronics Live Chat. How may I assist you today?
you: Hi Brian, I
you: own a Bel pro rx65
you: and it gave an error
you: that said
you: selfcal4
you: or something like that
you: then it said service
you: required
you: what does this mean?
Brian: Thereare a number of things that may cause this ERROR message. Please besure that you are getting consistent voltage (does the lighter socketstay ON all the time? Does it do the same thing in other vehicles?). If the display reads "Service Required" not caused by the above, itmeans it has failed it's self-calibration and requires service. Pleasecall our Customer Service Department at 800-341-2288 and they will giveyou a repair authorization number and instructions on how to return itto us so we can take a look at your detector.
you: Oh i see. what's the cost for repair?
Brian: That is a $59.95 repair fee. To set that up, please call Customer Service at 800-964-3138, option 2.
you: and what cause calibration to fail?
Brian: If the reasons listed above don't sound like what's happening, then it would be up to a repair tech to figure out why.
you: I had left it in the car in hot weather. would this be a cause?
Brian: It's possible, over a long time in the heat to develop.
you: I can call either number correct?
Brian: Correct.
you: ok thanks

I called the number and they were helpful, told me to use a packing service like UPS and such. Insure it. And it would take about 5-7 days for them to work on it, another 3-4 days of shipping time.
Considering the reviews on the rx65 and the prices for detectors out there, and considering that they will also apply any software updates (bought mine in '06) the $60 repair fee is worth it for me.

I assume that you mean when you ask it to PLOT THE ROUTE to your destination, it is sending you the LONG WAY not the most direct way.
GPS algorithms for determining the path that should take you to your destination, usually leave a lot to be desired. If you can live without the turn-for-turn directions, you may find that your trips end up being more efficient, and can save you gas and time.

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.
