The brightness of the image tracks ambient brightness and dims the display as the ambient light decreases, making the image less obtrusive under reduced lighting conditions where high image brightness is not necessary for good viewability.
To use
1.Turn AutoDIM OFF with the Auto DIM OSD menu.
2.Set Brightness to desired value in brightest expected ambient light.
3.Turn AutoDIM ON.
4.Set the Dimming Range to desired value. (See discussion below.)
5.Close AutoDIM menu.
If the brightest ambient light is 150 or above as reported by the Auto DIM OSD menu (units are approximately in Lux, a common measure of illuminance, or lighting of surfaces by light sources), the brightness will not change when the Auto Dim feature is turned ON.
However, when the ambient lighting is less than 150, the display will immediately dim in response to the setting of the Auto Dim range and the ambient light:
•Dimming Range is a measure of how much the display will dim when ambient light is reduced.
•Dimming only occurs in the ambient light range of
•A Dimming Range setting of 100 means that the image brightness will be reduced to its minimum in total darkness conditions.
•A Dimming Range setting of 0 means that the image brightness will not be reduced at all under total darkness conditions.

Touchscreen Features and Use
Your Preh MCI Touch series touch display is equipped with a resistive touchscreen. Features of a resistive touchscreen that are important for your use are:
•Composition: The touchscreen is made of a thin (about 1/8”) sheet of glass overlaid with a layer of plastic. The resulting composite is placed in front of the LCD panel in your Preh MCI Touch Monitor.
•Activation: The touchscreen can be activated by anything that applies a force of about 1 ounce over a normal
•Use and Abuse: The touchscreen plastic layer has a hard front surface coating on it, and will withstand years of use with fingers, fingernails and other relatively large radius styli.
However, hard objects with sharp edges can easily damage the touchscreen. Avoid the use of
•Cleaning: The touchscreen may be cleaned with common glass cleaners, but do not use cleaners with
•Application Use: One characteristic of the resistive touchscreen technology is that it averages multiple touches. So, If you touch the screen with two fingers at the same time, on opposite sides of the display, the reported location to the application will be in the middle of the screen! Consider this in navigation of your application.
