CAL7 is a broad self-test failure code. It will have to be sent to Escort for diagnostics on the specific problem unfortunately.

Needs to be re calibrated, escort can do that for you, so give them a call.

I just had this same problem. It's an easy fix. The "washers" that fell out aren't washers, they're the reason that the button fell into the unit. They are plastic "rivet heads" from the way the frame of the button is melted onto the cover. You can throw them away. I used super glue to re-attach the button to the cover.

call escort and order a speaker 800-964-3138

Hey guys, me again....Deadcandance..... I posted my trouble on a Satellite forum I belong to and I had a suggestion which I tried. And it worked!!!!! No manufacture returns, no cost at all, what I did was tokk it apart gently ...watch how everything comes apart so that you can reassemble again....

Start by getting a couple Q-Tips (Ear Swabs).Leave them dry so they won;t leave any residue on the diodes. Gently clean the horn, than clean/wipe the electronics board, and blow out the diffusion screen (leave the spit in your mouth). After I wiped the unit down, I didn't see any dust persay or dirt on the Q-tip but whatever I did, fixed it....
It worked for me. Took 15 minutes to do and I have been using the Radar for three months and not one false alarm in Laser mode.
Good luck...

it means that something on the main board went out call escort or return it if its new. and underwarrenty otherwise you will have to buy a new one. sorry for the bad news.

If the unit displays "Service Required" it needs to be returned to Escort for service. Contact them at www.escortradar.com or call 800-964-3138

you will have to call escort to see if they have parts available.

False alarms are common with most radar detectors. You may need to adjust your detector's settings to compensate for the interference that sets off the alarm. Check your user's manual for instructions on using the menu.

The problem with your Escort radar is the charging port. It is slacked and need to be replaced. That is why, when you are connecting your charger to it, you have to adjust it to get the proper fitting. Once you plug in a charger into any device over a period of time, it tends to loosen grip and contacts bit by bit It can take years to arrive at the slack point.
SOLUTION: First try cleaning the contacts/charging port, if that does not solve the problem, then it means replacing the contacts/charging port is the last resort.

Hi,

"Service required" means that the detector failed the self test when it was powered on. You need to call Escort at (800) 964-3138 and see if they are able to repair it. Unfortunately, this is not a DIY and you need to call Escort for the same.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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!

you might as well check if you can turn on using only the battery. If it wont, then try to push the power button for 8 secs after you remove the battery and power cord. Then reinsert power cord, and turn it on. If it still no good, then call escort because this issue is something to do with the system board inside of it. It does not react to the situation wherein you have plug the working power cord and a working battery.

Simple test: cover all the laser sensors with black tape - if the warning is still there then the unit is defective. In that case the only thing you can do is to take it to a dealer to have it tested and (if it's still in the warranty period) replaced.

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.

Hi

Please check this related link regarding your query :-

Unscrew the three screws, pop the three components apart (it really is a no-brainer since they only fit back together one way. Use canned air to blow everything out and just use the Q-tip on the front window and the parts that looked like the detector window internally.

Please accept the solution if it’s helpful. Do get back to us for any further query.

I use one of these for my public service scanner -

That fuse is a 2Amp fuse. ANY 2 Amp fuse that fits will do. Look even a single strand of wire will work in a pinch, simply twist it around body of old fuse and your good to go. As an aside here make sure you know what "Blew" the fuse before you simply "Replace it". Otherwise it will happen again. A Garage or electronics shop should have them.,
