The Touchkit software utility consists of tabs that allow you to determine the best settings for your touch screen

configuration.

The Tools tab provides access to calibration and touch position tools.

NOTE: Your touch screen is configured and calibrated at the factory. However, if you notice that the calibration is not as

precise as you would like, you can use the 4 Points Calibration tool to align the touch screen. For further details on

providing more accurate calibration using the Linearization Tool, please refer to the XFR630 with Touch User's Guide.

4 Points Calibration – Calibration aligns the touch panel with the video screen. The touch screen must be

calibrated to allow for positional accuracy of the stylus or finger touch inputs.

The 4 Points Calibration tool pops up a new window to guide you through the 4 points calibration. You should

follow the guide to touch and hold the blinking X symbol in the calibration window until it does not blink to make

sure that the utility can gather enough data for computation. In addition, a time line bar is shown in the bottom of

the window to indicate time elapsed. If the touch screen is not touched before the time line bar reaches the right

end, the calibration task will be terminated automatically.

Using a Battery

NOTE: For information about the warranty for your computer, see the Limited Warranty document.

For optimal computer performance and to help preserve BIOS settings, operate your portable computer with the main

battery installed at all times. One battery is supplied as standard equipment in the battery bay.

NOTE: Because the battery may not be fully charged, use the AC adapter to connect your new computer to an

electrical outlet the first time you use the computer. For best results, operate the computer with the AC adapter

until the battery is fully charged. To view the battery charge status, see 'Accessing Power Options Properties' in the

XFR630 with Touch Fully Rugged Notebook User's Guide.

NOTE: Battery operating time (the time the battery can hold a charge) decreases over time. Depending on how

often the battery is used and the conditions under which it is used, you may need to purchase a new battery during

the life of your computer.

Battery operating time varies depending on operating conditions. You can install an optional second battery in the XBay to

significantly increase operating time.

Operating time is significantly reduced when you perform operations including, but not limited to, the following:

Using optical drives

Using wireless communications devices, PC Cards, ExpressCards, media memory cards, or USB devices

Using high-brightness display settings, 3D screen savers, or other power-intensive programs such as complex 3D

graphics applications
