Press Fn and Bluetooth 1, 2 or 3 at the same time to enter pairing mode. Turn on Bluetooth on your device and select "B.O.W" in the list. Some Android phones show a code such as 19:16:4A:77:9E:D3 instead of the name, so check the code against the one shown on your keyboard's Bluetooth screen.
The built-in 160mAh battery charges in about 2 hours and gives up to 45 hours of continuous typing or up to 90 days of standby. It sleeps after ten minutes of inactivity and wakes with one click.
The stand is intended for lightweight devices such as phones. Heavier devices like iPads need a separate stand. This doesn't affect Bluetooth connectivity.
The stand isn't suited to very thick cases on phones and iPads, so take thick cases off or check that your device sits securely.
It weighs about 165 g (5.8 oz), opens to a 7.9-inch keyboard just larger than your palm, and folds into a slim strip roughly 2 to 3 fingers wide.
