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
