Model

LC-15S4U

Check item

• The reception may be weak.

• The quality of the broadcast may also be bad.

• Make sure the antenna is facing the right direction.

• Make sure the outside antenna is connected.

The picture is not sharp.

The picture moves.

The picture is doubled or tripled.

• Make sure the antenna is facing the right direction.

• There may be reflected electric waves from mountains or buildings.

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.

• 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)
