The touch screen display is an active color LCD unit capable of supporting VGA graphics modes. Display size is 240 x 320 pixels in portrait orientation. The covering is designed to resist stains. The touch screen allows signature capture and touch input. A pen stylus is included. The touch screen responds to an actuation force (touch) of 4 oz. of pressure (or greater). The color display is optimized for indoor lighting. The display is black when the device is in Suspend Mode or when both batteries have expired and the unit is Off.

When the Backlight timer expires the display backlight is turned off. The default value for the battery power timer is 3 seconds. The default value for the external power timer is “never” and the checkbox is blank.

The backlight timer dims the backlight on the touch screen at the end of the specified time.
