™ Dell Latitude™ XT2 XFR Service Manual 1 XT2 XFR Features 1.1 XT2 XFR User Modes 1.1.1 Notebook Mode Your XT2 XFR can be used either in notebook mode or tablet mode. To use your XT2 XFR in notebook mode, open the display until it reaches a comfortable viewing angle as in the image to the above, and use the keyboard and display as you would those of any other notebook computer.
When you convert your XT2 XFR between notebook and tablet modes, the screen orientation of your XT2 XFR will automatically change according to the settings you have established in the Dell Control Point System Manager application or the Windows Vista Pen and Tablet settings application, most commonly from landscape (notebook mode) to portrait (tablet mode).

Dell You can use the writing pad, the character pad, or the on-screen keyboard to enter text. The writing pad and the character pad convert your handwriting into typed text. The on-screen keyboard works just like a standard keyboard except that you enter text by tapping keys with your tablet pen. The following table describes the different choices for using the Input Panel.
Dell 1.3.2.2 Touch Usage One of the key advantages of the XT2 XFR is the ability to easily switch from pen input to touch input. When you use Touch Mode, a translucent image of a computer mouse, called the touch pointer, floats beneath your finger. The touch pointer has left and right mouse buttons that you can tap with your finger.

Dell 1.5 XT2 XFR Pen Your XT2 XFR uses a specifically designed electrostatic pen or stylus for use in tablet PC mode. Instead of relying on battery power, the energy source for the stylus is magnetic energy produced by the excitation coil built into the digitizer itself. The signal from the coil is picked up by the stylus and triggers the stylus to transmit an electric field.
