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.
