TouchPad Basics (with fingerprint reader)
The following items show you how to use the TouchPad with Acer Bio-Protection fingerprint reader:
•Move your finger across the touchpad (1) to move the cursor.
•Press the left (2) and right (4) 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.
•Use Acer Bio-Protection fingerprint reader (3) supporting Acer FingerNav 4-way control function 
(only for certain models) to scroll up or down and move left or right a page. This fingerprint reader 
or button mimics your cursor pressing on the right scroll bar of Windows applications.
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.
