System Use an optional A-B RF switch (not supplied) to switch between the cable
and over-the-air antenna programming, as indicated below.
This TV is capable of receiving unscrambled digital programming for
both cable (QAM and 8VSB) and external VHF/UHF antenna (ATSC).
It is strongly recommended that you connect the CABLE/ANTENNA
input using a 75-ohm coaxial cable to receive optimum picture quality. A
300-ohm twin lead cable can be easily affected by radio frequency
interference, resulting in signal degradation.
