Step 2 - Refresh:
If your equipment has already been activated, but you need to refresh the signal to it for it to start working, navigate to the "My Equipment" section of your account. You will see your equipment listed there. Verify all of the information looks correct.
Then, select the "Refresh Receiver" link next to the box that needs a refreshed signal. For multiple receivers, you will have to repeat this process for each box.
