TouchPad Basics (with fingerprint reader)
The following items show you how to use the TouchP ad 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 locat ed beneath the touchpad to perform selection and 
execution functions. These two buttons are simila r to the left and right buttons on a mouse. 
Tapping on the touchpad is the sa me as clicking the left button.
• Use Acer Bio-Protection fingerprint reader (3) s upporting Acer FingerNav 4-way control function 
(only for certain models) or the 4-way scroll (3) button (only for certain models) to scroll up or down 
and move left or right a page. This fingerprint re ader or button mimics your cursor pressing on the 
right scroll bar of Windows applications.
NOTE:  When using the TouchPad, keep it - and your fing ers - 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.
