The LCD screen is manufactured using high-precision technology. The ratio of effective pixels is 99.99% or more. However, there may be some tiny black points and/or bright points (red, blue, green or white) that constantly appear on the LCD screen. These points do not affect the recorded picture in any way.

Do not place this unit with the LCD screen pointing toward the sun. Otherwise, the unit may be damaged.

To clean the LCD screen

To remove dirt or to clean fingerprints from the LCD screen, use an LCD cleaning kit (not supplied). When you use the LCD cleaning kit, do not pour the cleaning liquid directly on the LCD. Always soak the liquid in cleaning paper and wipe the LCD with this paper.
