Basics
Using the touch screen
• Do not allow the touch screen to come into contact with other electrical devices.
Electrostatic discharges can cause the touch screen to malfunction.
• To avoid damaging the touch screen, 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 touch screen idle for extended periods may result in afterimages
(screen burn-in) or ghosting. Turn off the touch screen when you do not use the
device.
• It is recommended to use fingers when you use the touch screen.
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 a finger.
