• Make sure the outside antenna is connected.
The picture is not sharp.
The picture moves.
• Make sure the antenna is facing the correct direction.
• There may be reflected electric waves from mountains or buildings.
• Is the unit receiving interference from other devices?
Transmission antennas of radio broadcasting stations, transmission antennas of
amateur radios and cellular phones may also cause interference.
•
Use the unit as far apart as possible from devices that may cause possible interference.
■ Cautions regarding use in high and low temperature environments
•When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed. This is not
a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a heater, as
this may cause the cabinet to deform and the LCD panel to malfunction.
Storage temperature: –4°F to +140°F (–20°C to +60°C)
The picture is spotted.
• There may be interference from automobiles, trains, high-voltage lines, neon lights,
etc.
• There may be interference between the antenna cable and AC cord. Try positioning
them further apart.
There are stripes on the screen
or colors fade.
