Pairing Bluetooth devices
You must first pair a Bluetooth device (such as a keyboard or headphones) with iPad before you can use it.
Pair a Bluetooth device with iPad:
1 Follow the instructions that came with the device to make it discoverable.
2 In Settings, choose General > Bluetooth, and turn Bluetooth on.
3 Select the device and, if prompted, enter the passkey or PIN number [the keyboard will pop up on the iPad]. See the instructions about the passkey or PIN that came with the device.
Note: Before you pair an Apple Wireless Keyboard, press the power button to turn the keyboard on. You can pair only one Apple Wireless Keyboard with iPad at a time. To pair a different keyboard, you must first unpair the current one.
After you pair the keyboard with iPad, the product name and a Bluetooth icon appear on the screen.
