Not all Kyocera machines come with a hard drive or compact flash card installed in them by default. This is a requirement for embedded applications to run on these devices. If you try and install our embedded Kyocera application and the device does not have internal storage then you must install a compact flash drive. This is so our application has somewhere to store data and install successfully.
