Cautions regarding use in high and low temperature environments
• When the TV/DVD 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 TV/DVD will recover when the temperature returns to normal.
• Do not leave the TV/DVD in a hot or cold location. Also, do not leave the TV/DVD 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: – 4°F to +140°F (– 20°C to +60°C)
