My escort passport 8500 says "service required" after it starts up. what do i do?

Your radar detector is detecting a problem with part of the circuit during the start up - or boot sequence. Typically, these complex devices run a quick diagnostic check when starting up. If any result isn't as expected, you get a warning and in this case - a message indicating it needs servicing.

There is little that you can do to the detector to locate the problem; much less fix it. You could try to shut it off and turn on again to see if the problem goes away - but it probably won't. Your best bet is to return it to the factory for repair. You could continue to use it - but if the part of the detector that failed has to do with displaying or detecting radar sources, you may be in for an expensive surprise when you get pulled over for speeding.

Contact Escort radar customer service to go over your options.

I hope this helps - good luck!

Says to get service

The service message indicates something isn't working as expected. This usually happens right after powering on, when the detector runs its self-check and receives an unexpected result. Continuing to rely on this device for radar warnings could be expensive.

Contact Escort Radar Support to arrange for service to restore reliable operation.

I hope this helps.

Says service required when turn on

"Service required" means that the detector failed the self test when it was powered on. I would call Escort at (800) 964-3138 and see if they are able to repair it.

I got the Service Required message. What do I need to do?

The Service Required message indicates that your RD has repeatedly failed its attempts to perform self calibration of its radar detection circuitry. Only Escort can repair this issue.
