TROUBLESHOOTING (Continued)

Problem Check item

• The reception may be weak.

• The quality of the broadcast may also be bad.

• Make sure the antenna is facing the correct direction.

• Make sure the outside antenna has not been disconnected.

• Make sure the antenna is facing the correct direction.

• Broadcast waves may be reflected from adjacent mountains or buildings.

• There may be interference from automobiles, trains, high-voltage lines, neon

lights, etc.

• There may be interference between the antenna cable and power cable. Try

positioning them further apart.

• 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.

■ 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))

■ It is not a malfunction in the following cases.

• There are cases where reception of pictures is not good because of the distance between the main unit and Wireless Center, or

obstacles. Install the main unit and Wireless Center where you can get better pictures by changing the installation location or removing

obstacles.

• There may be bad reception of pictures if a microwave is being used nearby.

• Microwave units and the use of the so called “blue tooth function” (W LAN) on cellular phones or notebooks may impair the quality of

the transmission. If this is the case, switch these devices off.
