Use in hot and cold rooms (locations)
●
When the unit is used in a low-temperature room location, 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 Liquid
Crystal panel to malfunction. (Storage temperature: -20¡C to +60¡C)
