Press the headset's power button to turn it on. If the headset isn't fully charged, you might also want to connect it to its charger to ensure that it stays on during the connection process. Click the Windows logo in the bottom-left corner of the screen. The Start window will appear. Click the gear-shaped icon in the lower-left side of the Start window. It's a computer monitor-shaped icon in the middle of the Settings page. This tab is in the upper-left side of the Devices page. It's below the "Bluetooth" heading near the top of the page. Doing so will switch Bluetooth to On. If the Bluetooth switch is blue (or your computer's default color), Bluetooth is already on. It's at the top of the page. Doing so opens the Bluetooth menu. You'll find this at the top of the Bluetooth menu. This button's location will vary depending on your headset model. Most pairing buttons have a Bluetooth icon next to them or on them. Consult your headset's manual if you can't find the pairing button. It should appear in the Bluetooth menu within a few seconds. The headset's name will likely be a combination of the manufacturer's name and the headset's model number. If the headset doesn't appear in the Bluetooth menu, turn the Bluetooth off, press the pairing button on your headset, and then turn Bluetooth back on. It's below the headset's name. Clicking this should prompt your headset to connect to your computer at this point. After this is done, your headset is ready to be set up in Windows settings.
