How the G-sense pad works
The G-sense pad is a five-by-five grid of 25 small buttons which correspond to elements shown on
the display such as lists and buttons.
For example, if you touch the buttons shown in the illustration with your thumb, the cursor shown
on the display moves accordingly.
1
Pressing the button selects the item or button under the cursor on the
display.
2
When you touch a button, a cursor appears at the corresponding
positions on the display. When you move your finger, the cursor moves
accordingly.
By default, the G-sense pad is set up to work best using with your thumb.
You can change this setting or set the sensitivity again if the G-sense pad is not
responding properly.
Note
If you touch the G-sense pad with several fingers at the same time, it will not operate properly.
