Operating Your
Tablet
Chapter 2
13
This chapter provides information about the use of the Tablet.
If you are new to Tablets, reading this chapter will help you learn the operating
basics. If you are already a Tablet user, you may choose to read only the parts
containing information unique to your Tablet.
CAUTION：
● Do not expose your skin to the Tablet when operating it in a very hot or cold
environment.
● The Tablet can get uncomfortably warm when you use it in high temperatures. As
a safety precaution in such a circumstance, do not place the Tablet on your lap or
touch it with your bare hands for extended periods of time. Prolonged body contact
can cause discomfort and potentially a burn.

The following table shows how you use the touchscreen to obtain equivalent
mouse functions.

Using the Touchscreen
CAUTION：Do not use a sharp object such as a ballpoint pen or pencil on the
touchscreen. Doing so may damage the touchscreen surface. Use your finger or the
stylus.

objects that have conductive properties, such as fingertips and a capacitive-tipped
stylus. You can navigate on the screen without using a keyboard, or mouse.
