Welcome to Beltronics Live Chat. How may I assist you today?you:
Hi Brian, Iyou:
own a Bel pro rx65you:
and it gave an erroryou:
or something like thatyou:
then it said serviceyou:
what does this mean?Brian:
Therearea number of things that may cause this ERROR message. Please besurethat you are getting consistent voltage (does the lighter socketstay ONall the time? Does it do the same thing in other vehicles?). If thedisplay reads "Service Required" not caused by the above, itmeans ithas failed it's self-calibration and requires service. Pleasecall ourCustomer Service Department at 800-341-2288 and they will giveyou arepair authorization number and instructions on how to return itto usso 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:
Icalled the number and they were helpful, told me to use a packingservice like UPS and such. Insure it. And it would take about 5-7 daysfor them to work on it, another 3-4 days of shipping time.
Consideringthe reviews on the rx65 and the prices for detectors out there, andconsidering that they will also apply any software updates (bought minein '06) the $60 repair fee is worth it for me.
