Precautions when connecting the antenna

¥Use a coaxial cable which is free from

interference. Avoid using a parallel flat wire as interference may occur, causing the reception to become unstable and noise to appear on the screen.

¥Avoid using an indoor antenna as this may be affected by interference and poor reception.

¥Cable distribution system should be grounded

(earthed) in accordance with ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable.

¥ Keep the power cord as far away from the antenna wire as possible.

¥ Auto Tuning. Please refer to page 29.
