Hi
According to the ifixit [[Topic:Monster M7 Tablet]] guide (scroll down to ''Description'') there is a user manual installed on the tablet.
Alternatively, here’s a link to the [https://fccid.io/ZFN-M7/User-Manual/User-manual-2060464|Monster M7 Quick Start Guide] that may help. Allow a bit of time for the webpage to load and then just scroll down past all the advertising etc, to view the guide.
