Due to variations in paper type, text type and color and the
background color of documents or books that you are reading, you
may need to adjust the contrast to read the documents or books
clearly.
You can adjust contrast by using the Contrast Increase/Decrease
buttons on the control panel on the main body.
Or press the Enter button and Zoom In/Out button simultaneously
on the wireless controller.
