Precautions when connecting the antenna
• Please use a coaxial cable which is free from interference to connect the antenna. Avoid using a parallel flat feeder wire as interference
may occur, causing reception to be unstable and stripe noise to appear on the screen.
• Avoid using indoor antenna as this may be affected by interference. Please use CATV net or outdoor antenna.
• Keep the power cord as far away from the antenna wire as possible.
If there are noise appearance in the picture of VHF-Low band channel, please use the double-shielded cable (not provided) for RF LEADS to
reduce the noise.
