Tapping and Typing
To navigate the handheld computer, you must use the stylus. The stylus
works similar to a mouse on a regular desktop machine, but instead of
clicking an icon, you tap it. The first time the handheld computer is
turned on, a setup screen is displayed with instructions. These
instructions include a calibration setup that aligns the internal circuitry
with the touch sensitive screen.
Note: Make sure you always use the stylus when touching the screen. If
you use another device, the screen may become scratched.
The stylus can also be used to drag and select text on the screen. Simply
press the stylus to the screen and drag it across the characters without
lifting from the surface. Highlighted text indicates it has been selected.
Typing
Included in the handheld computer is a fully functional on-screen
keyboard. To access the keyboard, tap either the alpha or numeric icons
listed on the bottom of the screen in the Graffiti text area. Once the
keyboard is displayed, use the stylus to select the letters or numbers
desired.
