The TV sometimes makes a
cracking sound.

This is not a malfunction. This happens when the cabinet slightly expands and contracts

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.
Storage temperature:
l
20°C to
e
60°C.

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.
Go to “MENU” > “Setup” > “Child Lock” (Page 10).
Enter “3001” to cancel out the current PIN.
The PIN resets to the factory preset “1234”.
