A momentary press of either the “+” (plus) or “-“ (minus) buttons button will make a minor change in the image. If either button is
pressed and held, the changes made will be gradual and continuous. Ultimately, the image quality should improve to a
satisfactory level. Once the adjustment is made, it should not be necessary to change it again, as the new settings are stored in
memory and become the default settings with each startup.

If the image still lacks definition, configuration adjustments may need to be made to the attached video display equipment. This is
a problem most often seen in LCD displays. Check the manual for the equipment having the poor display and look for an "auto-
adjust" or "auto-configure" feature. Once this is done, you may need to repeat the Video Adjustment procedure described
above to achieve the best image.
