If Bluetooth is not already enabled on your PC, toggle the switch to turn it On.

Click the button with the plus icon labeled Add Bluetooth or other device.

A new window will pop up. Choose Bluetooth as the type of device you want to add.

Windows will scan for nearby devices. Wait for your device's name to appear in the list.

Click on the name of your specific Bluetooth device to initiate the connection.

Follow any on-screen instructions. You may need to enter a PIN or simply confirm the pairing.
