Note:
Using a PDA Stylus
provides higher accuracy to
the touch screen interface.
• At the next screen, touch in the center of the cicle displayed in the
upper left corner. Release the touch to move to the next alignment
circle. The tip of a stylus is suggested to successfully complete the
alignment by being on-target more accurately than by using a finger
tip. Exercise care to prevent puncturing the screen’s membrane,
which will void the instrument warranty. Figure 5-31 shows the
