Turning on the unit
Turn the computer on by quickly depressing the yellow on/off button on
the upper right-hand side of the computer (press for 1-2 seconds).
Note: Holding the on/off button down for a longer period of
time (5+ seconds) causes an emergency forced shut down
of the computer.
The Hammerhead will perform self-checking routines during the start-up
process. All units are configured at the factory to automatically boot to
the Microsoft Windows Desktop unless a custom configuration has been
requested.

Touch Screen, see page 14 for Touch Operations)
The pen is the primary screen navigation and data entry tool for the
Hammerhead. Without a keyboard attached, the pen is the only
means of communicating with the computer. Do not lose or
misplace the pen. The pen is usually tethered to the unit or its carrying
case. All users are encouraged to purchase a spare pen as a backup.
The pen functions like a two-button mouse. There are two switches in
the pen, one in the pen tip and another on the barrel of the pen. The tip
switch performs the same functions as the left button on a mouse and
the barrel switch performs like the right mouse button. Very few

applications require the use of the pen’s barrel button. Do not depress
the barrel switch when writing on the display; it will adversely affect
handwriting recognition.
To activate the tip switch, simply press the tip of the pen against the
display. This is similar to clicking the left button of a mouse. Double
clicking is accomplished by double tapping with the pen. Move an icon
by pressing the pen directly overhead and dragging the icon to the
desired destination, keeping the pen in constant contact with the display.
For right click functions, just depress the switch on the side of the pen. In
addition, XP Tablet PC Edition allows right click via pressing and holding
the stylus on the screen for 1+ seconds. Press and hold is an optional
feature. You can turn the feature on or off by going to Control Panel, and
then Tablet and Pen Settings.
Tapping the pen requires only light to moderate pressure. It is possible
to damage the pen by pounding the tip against the display with force.
Most problems using the pen are related to tapping speed and the
tapping area size. When using XP Tablet PC Edition, attributes related
to use of the pen (e.g. tap speed) can be adjusted by clicking on Control
Panel, Tablet and Pen Settings, and then the Pen Options tab. You can
also improve handwriting recognition accuracy by indicating if you are
right or left handed on the Settings tab. For Windows XP Pro operating
systems, look in the PenOffice tools folder found in the Windows
Program list.
The Hammerhead utilizes a proximity-sensing electromagnetic digitizer.
This component tells the computer the pen’s exact position. The
computer senses the pen as it nears the display and the cursor appears
when the pen is approximately an inch away. This allows visibility of the
exact location of input before making actual contact with the display.
The location of the cursor on the display is the location of input
regardless of the location of the pen tip. The cursor and the pen tip
should be closely aligned when the pen is in contact with the display. If
the pen and the cursor are out of alignment, click on Control Panel,
Tablet and Pen Settings and go to the Settings tab where you can
calibrate the screen for both landscape and portrait orientations. If you
are using Windows XP Pro, follow the instructions provided in the
PenOffice tools folder found in the Windows Program list. Confirm the
display is on the appropriate setting before attempting to realign the pen.
