If this sounds like a dashboard alert for a fault then you need to have your car diagnosed by a computer to find the exact fault.It works out to be cheaper..Check digimotolite on google ...

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.
