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 Liquid Crystal panel to malfunction.
Storage temperature: f 4°F to e 140°F ( f 20°C to e 60°C)

• To enjoy HD images from external equipment, you are required to set up HDMI
connection or component connection.
• If the program content is not of HD quality, HD images cannot be displayed. Check
that the program you are viewing provides HD images.
• The HD cable/satellite set-top box may need to be confi gured to output HD images
via cable/satellite.

performance.
