Maintaining the PPT 2800
For trouble-free service, observe the following tips when using
your PPT 2800:
• Do not scratch the screen. Use the supplied stylus or plastic-
tipped pens intended for use with a touch-sensitive screen.
Never use a pen or pencil or other sharp object on the
screen.
• Although your PPT 2800 is water and dust resistant, do not
expose it to rain or moisture for an extended period of time.
Treat your PPT 2800 as you would a pocket calculator or oth-
er small electronic instrument.
• The touch-sensitive screen of your PPT 2800 contains glass.
Do not drop your PPT 2800 or subject it to strong impact.
• Protect your PPT 2800 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 or use your PPT 2800 in any location that is ex-
tremely dusty, damp or wet.
• If the surface of the PPT 2800 screen becomes soiled, clean
it with a soft cloth moistened with a diluted window-cleaning
solution.
