or touch screen input, use the included stylus or your finger. The method you choose depends on which one
is appropriate for your application. While there is a great deal of variation in different applications, for buttons
or icons that are close together, you generally achieve greater accuracy with the stylus. Use of other objects,
such as paper clips, pencils, or ink pens can damage the input panel and will void the warranty.
Hand Held Products recommends using screen protectors to protect the touch screen; especially when used with
applications that require high-volume interfacing with the touch screen. Screen protectors help prevent damage to
the touch screen display and are easily installed. Screen protectors can be purchased at any major computer retail
store or directly from Hand Held Products; contact Hand Held Products directly for part numbers and pricing.
