• There may be interference between the antenna cable and power cable. Try positioning them further apart.

There are stripes on the screen or colours fade.

• Is the unit receiving interference from other devices? Transmission antennas of radio broadcasting stations and 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.

■ Use in hot and cold rooms (locations)

•

When the unit is used in rooms (locations) with low temperature, 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: –20˚C to +60˚C)
