Tips for Highlight Zone
1.To protect CDT against the screen brightness, the Highlight Zone function persists for three hours and then automatically stops. So please reset it to continue.
2.Once the Highlight Zone has been switched off, you can't select any of the other menus within the Hightlight Zone.
3.When the Highlight Zone function is operated, the surrounding brightness of screen may become dark.
4.Depending on the video card you use, a color saturation phenomenon may occur in the Highlight Zone. In this case, slightly lower the contrast of the Highlight Zone and the color saturation will be reduced.
Note: If problems repeatedly occur, contact an authorized service center.
