Congrats, you just got yourself the longest range radar detector available on the market today, notwithstanding $5000 systems that install in your bumper. This is my hobby so I have a few recommendations for you to get maximum performance from it.
First of all, I highly recommend changing some settings on it in order to unlock the full potential of the detector. What I'm going to recommend is that you turn RDR off, and apply expert segmentation settings to disable sections of the Ka band spectrum that police do not use. Although RDR on does prevent Cobras from alerting on your Redline, it also chops about half the range off of it as well. Disabling RDR is an instant range boost for Ka band.
To apply the band segmentation settings, go into the menu and turn KaSW OFF, which will then allow you to individually select 10 different segments of the Ka band to enable or disable. In the United States, police radar is found on 3 different segments: 2, 5, and 8. All the rest can be turned off. Turning off the other segments also gets you an additional range boost on Ka band. Thus, the final setting would be KaSW off, seg 1 off, seg 2 on, seg 3 off, seg 4 off, seg 5 on, seg 6 off, seg 7 off, seg 8 on, seg 9 off, and seg 10 off.
In some areas, the police run some guns that appear in other segments, most notably seg 6. However, these guns only appear in this segment because they are out of tune and have not been calibrated, which is something that could be won in court rather easily.
In some states (most notably Ohio), there are Traffic Sensors installed on the highways every mile or so to sense the average speed of traffic (they don't give out tickets). These can be an annoying nuisance, because they will set off K band on your detector. If your state has these, or if you suffer from a huge number of luxury cars with Blind Spot Monitor systems, you can turn TSR ON to help filter them out. This applies a delay to K band to prevent spurious signals from alerting you.
You can check out other information about your area by going to the Geographical Survey here:
https://www.rdforum.org/wiki/index.php?title=RDF_Geographical_Survey and searching for your state and county. Keep in mind that if Laser is heavily in use in your area, a laser detector will not help because laser gets your speed before you can react to the alert. The only defense there is to drive under the cop's speed threshold or spend more money on a laser jamming system.
Enjoy!
