15. When the mouse batteries reach Low or
Critical, a warning message will also be
displayed on the Today screen.
16. If the mouse driver fails to detect a
supported Bluetooth stack during the initial
setup or at a later time (e.g. after power
on), it will display the Bluetooth system
not detected message on the Connection
page. This should not happen on Pocket PC
devices with a built-in Widcomm stack
version 1.4.x or later or Microsoft stack,
since it is always present and is supported
by the mouse software. However, if the
device has an incompatible version of the
stack, this message may be displayed or the
software may function improperly. In this case
the mouse software must be replaced with an
updated version.
