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 keyDescription
Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock  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.
