Cautions regarding use in high and low temperature environments
When the TV 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 TV will recover when the temperature returns to normal.
Do not leave the TV in a hot or cold location. Also, do not leave the TV 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: + 5 °C to + 35 °C.
