Scroll down to “SAVE” and click the left button. The screen will refresh after a second confirming the save.
Click menu again to exit the menu. Click the UP, DOWN, LEFT, and RIGHT buttons to center the display (you may need to enter the menu again to change the size). Once done, click the SAVE button. The screen will refresh after a second confirming the save.
