Maintaining the Device
For trouble-free service, observe the following tips when using the device:
• In order to avoid scratching the screen, use plastic-tipped pens intended for use with a touch-sensitive
screen. Never use an actual pen or pencil or other sharp object on the surface of the device screen.
• The touch-sensitive screen of the device is glass. Do not drop the device or subject it to strong impact.
• Protect the device from temperature extremes. Do not leave it on the dashboard of a car on a hot day,
and keep it away from heat sources.
• Do not store the device in any location that is dusty, damp, or wet.
• Use a soft lens cloth to clean the device. If the surface of the device screen becomes soiled, clean it
