Cautions regarding use in high and low temperature environments

When the unit is used in a low temperature space (e.g. room, offi ce), 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: f20°C to e60°C.
