The device is relatively small, lightweight and can be updated via the Internet. The software must be downloaded from the manufacturer's Web site for this purpose. Translation of the manual and in the display of the device (firmware) is not perfect, but overall course. In the German instructions are cautioned not to let the battery in the device when it connects via USB. Of course, non-rechargeable batteries are meant who would otherwise loaded - and that must not happen, of course. I pointed the manufacturer on the translation error, perhaps this will be corrected in the future. The unit can be set so that it turns itself off after a set time - or, alternatively, only the screen. When the screen is off, and the speaker is disabled.
