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 LCD panel to malfunction.
Storage temperature: –20°C to
e
60°C.
Enter “3001” when PIN entry is required.
• This operation cannot be performed from the DTV menu screen.
Restore the current PIN under “Change PIN” (TV menu > Setup > Child lock).
