Touch Screen Display
The display is a LCD (Liquid Crystal Display) with a Capacity touch screen. The 3.5” VGA (Video Graphic Array) is
transmissive active matrix color and backlit. The resolution is 480 x 640; see Display Backlight on paragraph 4.4.
For touch screen input, use the stylus included with the terminal or your finger. The method you choose depends
on which one is most appropriate for your application. While there is a great deal of variation in different
applications, you generally achieve greater accuracy with the stylus for buttons or icons that are close together.
WARNING: Use of objects, such as paper clips, pencils, or ink pens on the touch screen can damage the input panel and may cause damage
not covered by the warranty.
4.4. Display Backlight
The intensity of the backlight of the touch screen display may be changed, and the backlight may be programmed to turn
off after the terminal has been idle for a specified period of time.
To adjust the intensity of the backlight while on battery power, tap Start -> Settings -> System -> Backlight.
Screen Backlight - Battery/External Power
Move the slider to adjust the screen backlight while on battery power.
You may turn the screen backlight off if the device is not used for a designated period of time by checking the option and
designating the desired time period.
You may also turn on the screen backlight when a button is pressed or the screen is tapped by selecting the appropriate
checkbox.
☞NOTE: Using the backlight option while on battery power substantially reduces battery life.
You may make the same changes when on external power by tapping the External tab.
