Tips for Everyday Use

Keep the numpad charged if you plan to use it wirelessly; the battery indicator is not described in the supplied information, so periodic charging is wise. The hot-swappable PCB lets you experiment with different switches if the Kailh Box White V2 clicky feel isn't your preference. For calculator mode, the numpad works entirely on its own, so you can use it even when the computer is off.
