You can download the manual from that link. A lot of mods are overkill with modes and menus. Most people just vape in power mode or tempature control if using stainless steel coils. Site doesn't even say what the included coils are made of. Probably Kanthal which will not work in temp control.
You really don't need to mess with many settings (and even though it has temp control in the menu, none of the coils available can use it... just ignore that) If you are new to vaping just a few tips... prime coils and let sit for at least 10 minute before vaping and when using a new coil, start at lower power to break it in.
