If You Have Digital Cable without Cable Box or Antenna...
Make sure the power of HDTV is turned off.
Connect the RF cable from your antenna or digital cable to the TV port on the
back of your HDTV.
Turn on the HDTV.
Follow the first time on screen instructions.
Not all broadcasts are in High Definition (HD). Please refer to your local
broadcasting stations for more information.
The HDTV's tuner is designed for HDTV therefore requires a stronger signal than
normal TVs. If you cannot achieve that signal level with your antenna or cable, your
HDTV might lose picture or sound.
