Connect it to the coax line / outlet and power it up. Let it fully sync up with the system. Check that the front or the top panel indicator light(s) is / are steadily lit. Next step. I'm not sure if this method works anymore (YMMV). Try calling 1-855-652-3446. That is their self-install device activation line. Have the RF / CM / HFC MAC address and the serial number of it handy when you call. Good luck ! Please let me know.
