Why can't I set up Bluetooth on my Lenovo V570 laptop?

[tfd3]

I'm using Windows 10 on my Lenovo V570. When I navigate to "Bluetooth and other Devices" and click on "Add Bluetooth and other devices", I get a "Couldn't connect" message. It also suggests turning on Bluetooth, but I don't know how to do that. Please help.

Fn + F5 gets no response from my computer. At what screen should I be looking?
When I click on "Add a Bluetooth device" I get a message saying "Cannot connect."
