Controlling the touchscreen
•
Do not allow the touchscreen to come into contact with other electrical devices.
Electrostatic discharges can cause the touchscreen to malfunction.
•
To avoid damaging the touchscreen, do not tap it with anything sharp or apply
excessive pressure to it with your fingertips.
•
The device may not recognise touch inputs close to the edges of the screen, which
are outside of the touch input area.
•
Leaving the touchscreen idle for extended periods may result in afterimages
(screen burn-in) or ghosting. Turn off the touchscreen when you do not use the
device.
•
It is recommended to use fingers when you use the touchscreen.
Tapping
To open an app, to select a menu item, to press an on-screen button, or to enter a character
using the keyboard on the screen, tap it with your finger.
