The package includes the OZ-590, a single AAA battery, a printed
manual, a software CD, and a serial synch cable for your PC.
As far as I can tell from the reading I have done, and from looking
at other cables I have, this cable will fit only the OZ-590...
Sharp's internet advertising has a good picture of the OZ-590,
and you can clearly see how the plastic flip-over cover attaches.
I consider to be this easy-to-use cover a very good feature for
protecting the OZ-590's screen. In the photo the stylus appears
to be metal, but it is actually dark gray plastic. The stylus is
slightly longer than the OZ-800 stylus.
