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. When the Highlight Zone function is operated, the surrounding brightness of the screen may become dark. 3. 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. -1821” Fast Scan Tabletop User Guide 150-057 Section 8 SELF TEST FEATURE SELF TEST FEATURE CHECK 1.
