If you don’t pair your keyboard with your iMac within 3 minutes, the indicator light
and keyboard turn off to preserve battery life. Press the power (®) button to turn your
keyboard on again, allowing you to pair it with your iMac. Once you successfully pair
your keyboard with your iMac, the indicator light glows steadily for 3 seconds, and then
turns off.
