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 ½ to 1 second).

Note: Holding the on/off button down for a longer period of time (4-5 seconds) causes an emergency forced shut down of the computer.

The HAMMERHEAD RT 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.

Pen operations

The pen is the primary screen navigation and data entry tool for the HAMMERHEAD RT. 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. Attaching the tether to one of the zippers on the carrying case with a split ring allows the tether to be anchored on either side of the computer. By shifting the position of the zipper, the tethered pen is convenient for right or left-handed users. 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.

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 98/2000/XP Pro operating systems, look in the PenOffice tools folder found in the Windows Program list.

The HAMMERHEAD RT 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 98/2000/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.
