- Ensure your device (computer, tablet, smartphone) has Bluetooth enabled.
- On the underside of the mouse, press and hold the Connect button (often located near the optical sensor or power switch) for a few seconds until the LED indicator on the top of the mouse starts blinking rapidly. This indicates the mouse is in pairing mode.
- On your device, go to Bluetooth settings and search for new devices.
