② D&N Mode (Day & Night Mode)
Automatically detects the degree of darkness at night, or in poor lighting conditions, and so keeps the screen
bright and clear.
·Auto : When the Auto Mode is selected, it automatically switches to Color mode to maintain optimum color
during the day, and to Black and White mode at night for clearer pictures in poor lighting.
However, the Slow Shutter doesn't work in Auto Mode.
·Day : Maintains color images. The Slow Shutter function is activated in this mode.
·Night : Maintains black and white images. The Slow Shutter function is deactivated in this mode.
③ Slow Shutter
The Slow Shutter is activated only in Day Mode and keeps the screen bright and clear in low lighting
conditions.
Increase the level in the menu, and the maximum level can be adjusted. (X2~X128) The larger the scale, the
brighter the screen. However, the after-image of moving objects is also increased.
