USD 75 is what other used ESD 9210s are current going for here.

Yours appears to be an older model, but should have similar functions to the current generation. Heres the manual for a similar unit. If it helps, please remember to rate my solution.

• For a Cobra ESD-8200 Radar Detector you can choose from a strait cord or a coiled cord. It's just your preference/ Either will work.

• Part # 420-026-N-00 coiled cord is available here http://www.buyradardetectors.com/products/cobra/420026n001.aspx

• Part # 420-030-N-00 strait power cord is available here http://www.bestradardetectors.net/Cobra-Straight-Power-Cord.html

I dont know of any radar detectors that need to be calibrated. To calibrate the radar, you would need a source of RF energy like a radar gun and a ton of specialized equipment.
Just turn it on, place it up high enough on the windshield or dash so that it has a clear "view" of the road. Suction mounts on windshields get the detector higher and it offers you a better view and an earlier warning as it can "see" over the hill better.

Go to www.cobra.com select U.S. then support then radar detectors and your model is the first one. Right now downloads are "off line" their doing updates to their system. but they say it will be back up soon. Hope this helps

The following is a direct link to the PDF owners manual for your ESD 7000:

Of note, this extremely inexpensive radar detector provides just about the worst performance of any radar detector product currently available from any RD manufacturer. I suggest that you visit radardetector.net to learn more about radar detectors.

Here is a direct link to the PDF version of the ESD-7000 manual on Cobra's web site:
