Caring for your handheld
Your handheld is designed to be rugged and reliable and to provide years of
trouble-free service. Please observe the following general tips when using your
handheld:
■ Take care not to scratch the screen of your handheld. Keep the screen clean.
When working with your handheld, use the supplied stylus or 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 handheld screen.
■ Your handheld is not waterproof and should not be exposed to rain or moisture.
Under extreme conditions, water may enter the circuitry through the front
panel buttons. In general, treat your handheld as you would a pocket calculator
or other small electronic instrument.
■ Take care not to drop your handheld or subject it to any strong impact. Do not
carry your handheld in your back pocket: if you sit on it, you may damage it.
■ Protect your handheld from temperature extremes. For example, do not leave
your handheld on the dashboard of a car on a hot day or on a day when
temperatures are below freezing, and keep it away from heaters and other heat
sources.
■ Do not store or use your handheld in any location that is extremely dusty, damp,
or wet.
■ Use a soft, damp cloth to clean your handheld. If the surface of the handheld
screen becomes soiled, clean it with a soft cloth moistened with a diluted
window-cleaning solution.
