If you have just performed a firmware upgrade and are seeing Error 7 - No RF Comm. it is possible your 36M or 72M did not correctly load the 90M.s19 firmware file.
Please double-check the .s19 firmware file on your USB drive and reload.
To re-download the file you can either retrieve it as part of the upgrading process in our free COBRA reprogramming software, or as a direct download from the release notes page for the specific firmware version you're updating to.
Links to our release note pages can be found in the list of our official firmware versions here.
