To connect USB on the Key-Disp KD986, the manual mentions USB connection functionality but does not provide specific steps.

To connect Bluetooth:
1. Open the Key-Disp APP.
2. Enter the APP homepage.
3. Click "My-More Devices-Add Device."
4. Search for Bluetooth devices.
5. Select the display from the searched devices and click "Finish."
6. The display will show a symbol indicating a successful connection.
