add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered
in this generic service guide. In such cases, please contact your regional offices or the responsible
personnel/channel to provide you with further technical details.

TouchPad Basics
The following items show you how to use the TouchPad:
•Move your finger across the TouchPad (1) to move the cursor.
•Press the left (2) and right (3) buttons located beneath the TouchPad to perform selection and execution
functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the TouchPad is
the same as clicking the left button.
NOTE: When using the TouchPad, keep it - and your fingers - dry and clean. The TouchPad is sensitive to
finger movement; hence, the lighter the touch, the better the response. Tapping too hard will not
increase the TouchPad’s responsiveness.

Using the Keyboard
The keyboard has full-sized keys and an embedded numeric keypad, separate cursor, lock, Windows, function
and special keys.
Lock Keys and embedded numeric keypad
The keyboard has three lock keys which you can toggle on and off.
The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters
located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols
are not printed on the keys.
Lock key Description
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock
<Fn> + <F11> When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use
this mode when you need to do a lot of numeric data entry. A better solution
would be to connect an external keypad.
Scroll Lock <Fn> +
<F12> When Scroll Lock is on, the screen moves one line up or down when you press the up or down arrow keys respectively. Scroll Lock does not work with some
applications.
Desired access Num Lock on Num Lock off
Number keys on
embedded keypad Type numbers in a normal manner.
Cursor-control keys on
embedded keypad Hold <Shift> while using cursor- control keys. Hold <Fn> while using cursor- control keys.
Main keyboard keys Hold <Fn> while typing letters on
embedded keypad. Type the letters in a normal manner.
