Hi Tom, I really don't want to beat this to death, but.....OK, the "Checksum Failed, Restore Defaults" was due to my loading a Config file that did not have the Net Radar, etc. in it. I can understand that, but there was nothing that clearly told me what was causing the "Error" and the resultant CHECKSUM FAILED message. You are correct in that the system did not state that the firmware loading failed, but I had no idea what to do other than to perform a Restore Defaults function, per the verbal message. I did not know what caused the "Error" and the CHECKSUM FAILED message, I did not know what, if anything, had happened to the firmware/software in the system, or if it had been corrupted. From your advice last night, and today, it is now clear that I could have either Restored the Settings to the Default selections, or load a new Configuration file that contained the Net radar functions, which I did last night. Everything appears to be operating correctly, and a comparison of the system's Device Information and Profile A/B/C settings match my hard copies of my Configuration Profile A/B/C selections.

What does CRC stand for? If I remember correctly, I also saw it in a post last night. Thanks for the explanations, all is OK at this time.
