Touch Panel - Asus AST21 Basic Manual

■ Touch panel

● Use your finger to operate the touch panel. Do not use
ballpoint pens, pencils or other sharp-pointed objects. Using
such objects does not only hinder correct operation of the
touch panel, but also might cause scratching or damage to
the display.
● Do not put stickers or sheets (e.g. commercially available
protective films, peep prevention sheets) on the display. Doing
so might hinder correct operation of the touch panel.
● Do not operate the touch panel with fingernails. Doing so
might result in split nails or jammed fingers.
● If the display surface is dirty or wet with sweat or water, it may
not function correctly. In such case, wipe the display surface
with a dry, soft cloth.
● When carrying the product in your pocket or bag, take care not
to put the touch panel close to metals or other conductive
materials, as it might cause false operation of the touch
panel.
■ Internal battery
● Use in very hot or cold environments, for example, when left in
an automobile with the windows closed in summer, will cause
the battery capacity to drop and shorten the available battery
usage time. This will also shorten the battery's service life. Try
to use the internal battery as far as possible at room
temperature.
● Charge the battery before using the product for the first time
after purchase, or if you have not used the product for a long
time.
