Dell™ Latitude™ XT2 XFR Service ManualPage 16 of 94 Version A00-011.4.3.1.1 Input Mode SelectionThe N-trig applet has 4 operating modes:Pen Only — In this mode, the stylus is the only device that can be used as the input device with theN-trig digitizer. Changing from Pen Only mode to any other mode is done by clicking with an activeinput device on the N-trig Applet icon in the system tray. When the applet is open, select desiredmode and press OK.Touch Only — In Touch Only mode, a single finger is the only input device that can be used with theN-trig digitizer. Using the stylus is not possible. It is important to note that only a single hand contactis allowed with the digitizer for proper execution. Changing Touch Only mode into any other mode isdone by tapping the N-trig Applet icon in System Tray using a finger or other active input device andchoosing the desired mode. Press OK to confirm.Auto Mode — The N-Trig digitizer is capable of detecting a stylus as well as finger touch. The purposeof Auto Mode is to allow the user intuitive toggling between the Pen Only or Touch Only modes. Thedefault input device for Auto Mode is the stylus as long as it is in range of the tablet screen (hoveringin proximity or in contact). A basic principle in Auto Mode is that stylus detection in the digitizerproximity would turn the digitizer into Pen Only mode as an overriding priority. A double-tap fingergesture on the screen (similar in style to a mouse double-click) will switch the digitizer from Pen Onlymode to Touch Only mode. The system will remain in Touch Only mode as long as the stylus is out ofrange. Once the stylus is detected in range the system will automatically switch to Pen Only mode.Dual Mode (Vista Only) — Dual Mode is a unique operational mode that is functional only whileusing the Microsoft Vista operating system. In this mode, the OS switches automatically between theavailable pointing device according to its internal priority and attributes.1.4.3.1.2 Touch TuningIf you believe that the XT2 XFR's finger detectionfunction is not working properly, a recalibration of thetouch feature may be in order.
