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 LCD panel to malfunction.

IMPORTANT NOTE ON RESETTING THE PIN
We suggest that you remove the following instruction from the operation manual to prevent children from
reading it. As this operation manual is multilingual, we also suggest the same with each language. Keep it in a
safe space for future reference.
Enter “3001” when PIN entry is required.
Restore the current PIN under “Change PIN” (TV menu > Setup > Child lock).
