Notes:

- To restore all settings to their original status, select the option Reset to factory defaults in the Set Up menu.

- If the TV set is operated without sufficient ventilation, the internal temperature can rise excessively. If the ambient or internal temperature rises above a certain value, first of all, the warning window on the left-hand side of the screen will appear. As a result, the TV set may automatically switch to standby mode. Make sure sufficient ventilation is provided!
