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: –20°C to +60°C)
