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: –20°C to +60°C)
• The reception may be weak.
• The state of the broadcast may also be bad.
• Make sure the antenna is facing the right direction.
• Make sure the outside antenna is not disconnected.
• Make sure the antenna is facing the right direction.
• There may be reflected electric waves from 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 or
amateur radios, and cellular phones may also cause
interference.
• Use the unit as far apart as possible from devices that may
cause possible interference.
