After I hold the pairing button, the indicator light doesn't flash quickly and the mouse won't enter pairing mode — what should I do?

This is usually because you didn't press deeply enough to actually trigger the button. Please make sure you press the pairing button "firmly all the way down" and hold it for a full three seconds — the indicator light will then start flashing quickly and enter pairing mode. If there's still no response, first confirm the mouse is powered on and has enough battery, then try again.
