Software Operation
This chapter shows you how to improve performance of your computer
through screen calibration, battery maintenance and screen brightness
settings. It also covers some of the unique features and benefits of
Microsoft’s XP Tablet PC Edition Operating System, which comes
standard on Hammerhead RT Pen Tablets.
CALIBRATION
Pen Tablet Calibration
If you change screen orientations or sitting positions, it may be
necessary to recalibrate the pen settings. The pen should be calibrated
any time options in the tablet and pen settings are changed.
• Go to Start, Control Panel, Tablet and Pen Settings
• Tap the Settings tab
• Under Calibration, tap the name of the screen orientation for which
you would like to calibrate your tablet screen.
• Tap Calibrate
• Follow the on-screen instructions for calibrating the screen
• Note: You must calibrate the screen for each screen orientation separately.
Touch Screen Calibration
You can calibrate your touch screen anytime you notice it may be getting
out of alignment.
• Go to Start, All Programs
• Select Hampshire TSHARC Control Panel
• Under the Calibration tab, in the section marked “General Calibration,”
choose the Calibration Type (you can select a 3, 4, 7 or 20 point calibration)
and then select “Run” which will enable you to calibrate the touch screen.

Battery Performance and maintenance
Monitoring your battery
You can easily monitor your battery to see how much power you have
available while you are working away from your desk.
To check your battery power, double-tap the Power Meter icon in the
Windows system tray. The Power Meter icon appears as a battery when
your Tablet PC is running on battery power. The icon changes to a plug
when on AC power. You can monitor your battery as it charges to see
when it is fully charged.
Setting the battery alarm
You can set a warning alarm that is activated when your battery falls
below the levels you have defined as low and critical. You can change
the battery level at which the alarm or message is activated.
• On the taskbar, tap the Start button, and then tap Control Panel.
• Tap the Power Options icon.
• Tap the Alarms tab.
• Under Low battery alarm and Critical battery alarm, specify the
settings that you want by moving the slider.
• Tap Alarm Action to select the type of alarm notification and
resulting action you want. In the critical battery alarm section, under
Alarm Action, WalkAbout recommends a Shutdown or Hibernation
setting, not a Standby setting.
Turning off power-consuming peripherals
Peripheral devices on your computer use power. For instance, your
Tablet PC may have a wireless network connection, a modem card or
USB devices. Because some of these peripherals can draw a significant
amount of power, you should consider unplugging them or turning them
off in situations where you want to conserve battery power. For
information on turning off your wireless network connection, please refer
to the manufacturer's documentation.
