Each TV is connected to a small black CIK digital cable box. To watch TV make sure that both the CIK cable box and the TV are plugged in and turned ON. Make sure that the TV is set to correct input to watch Cable TV channels. Use digital cable box remote control to change TV channels. If cable TV stops working, the cable box might need to be unplugged, and after 30-45 seconds plugged back in to be restarted.
