Notes
• Use a coaxial cable to eliminate interference and noise from radio waves.
• Do not bundle the coaxial cable with the power cord or other cables.
• If the antenna is not installed correctly, contact qualified service personnel to correct the
problem.
• If the signal level for a channel is weak, the picture may be distorted. Adjust the antenna
or use a highly directional outdoor or set-top antenna with a built-in amplifier.
• If the picture quality is good on some channels and poor on others, the problem may be
caused by a poor or weak signal from the broadcaster or cable TV provider.
• If you connect to cable TV without a set-top box and experience poor picture quality, you
may need to install a set-top box to improve signal reception and picture quality. Contact
your cable TV provider about upgrading to a set-top box.
• Many high-definition (HD) channels upscale standard-definition (SD) content. The picture
displayed on your TV is still displayed as SD, thus the picture quality will not be as clear or
crisp as it would be if the content was originally recorded in HD.
