Picture defects and the reason
Snowy Picture
Snowy picture is usually due to weak signal. Adjust antenna
or install an antenna amplifier.
Double Image or Ghosts
Double images are usually caused by reflections form tall
buildings. Adjust the direction of the antenna or raise it.
Radio Wave Interference
Wave patterns are moving on the screen, which are usually
caused by nearby radio transmitters or short wave receiving
equipment.
High Temperature Electrothermal Interference
Diagonal or herringbone patterns appear on the screen or
part of picture is missing. This is probably caused by high
temperature electrothermal equipment in a nearby hospital.
