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

indicator on the TV does not light up, press POWER on the TV.
• Is the AC cord disconnected? (See page 7.)
• Has the power been turned on? (See page 16.)
• External influences such as lightning, static electricity, may cause improper
operation. In this case, operate the unit after first turning on the power of the TV or
unplugging the AC cord and replugging it in after 1 or 2 minutes.
