Touch screen

The touch screen shows calculation formulas, calculation results, graphs and other information. The stylus that comes with the ClassPad can be used to input data and perform other operations by tapping directly on the touch screen.

Stylus

This stylus is specially designed for performing touch screen operations. The stylus slips into a holder on the right side of the ClassPad for storage when it is not in use. For more information, see “Using the Stylus” on page 1-1-4.

General Guide

Using the Stylus

Most value and formula input, command executions, and other operations can be performed using the stylus.

Things you can do with the stylus

• This is equivalent to clicking with a mouse.

• To perform a tap operation, tap lightly with the stylus on the ClassPad’s touch screen.

Tap

• Tapping is used to display a menu, execute an on-screen button operation, make a window active, etc.

• This is equivalent to dragging with a mouse.

• To perform a drag operation, hold the tip of the stylus on the touch screen as you move the

Drag

stylus to another location.

• Dragging is used to change the setting of a slider or some other on-screen controller, to move a formula, etc.

Important!

• Be sure that you do not misplace or lose the stylus. Keep the stylus in the holder on the right side of the ClassPad whenever you are not using it.

• Do not allow the tip of the stylus to become damaged. Using a stylus with a damaged tip to perform touch screen operations can damage the touch screen.

• Use only the stylus that comes with your ClassPad or some other similar instrument to perform touch screen operations. Never use a pen, pencil or other writing instrument, which can damage the touch screen.
