Inside the small Sentry 2 box we found besides the panel itself and the cables attached to it two spare temperature sensors, installation screws, adhesive tape to attach the sensors and a piece of paper the manufacturer seems to call "user manual".

This so-called "manual" accomplished the feat of saying nothing useful in four different languages. There is no info on how to install the sensors nor how to operate the panel. And its operation is not as easy as it seems. It is really disappointing when a product comes with this kind of manual. At NZXT website we found an operation guide, but it is very brief too.
