Use AirPrint to print wirelessly to an AirPrint-enabled printer, from apps such as Mail, Photos, and

Bluetooth devices

You can use Bluetooth devices with iPad, such as stereo headphones or an Apple Wireless 
Keyboard. For supported Bluetooth profiles, go to 

For important information about avoiding hearing loss and avoiding distraction 

while driving, see 

 on page 123.

Note:  The use of certain accessories with iPad may affect wireless performance. Not all iPhone 
and iPod touch accessories are fully compatible with iPad. Turning on airplane mode may 
eliminate audio interference between iPad and an accessory. Reorienting or relocating iPad and 
the connected accessory may improve wireless performance.
Turn on Bluetooth. Go to Settings > Bluetooth.
Connect to a Bluetooth device. Tap the device in the Devices list, then follow the onscreen 
instructions to connect to it. See the documentation that came with the device for information 
about Bluetooth pairing. For information about using an Apple Wireless Keyboard, see 

 on page 25.

iPad must be within about 30 feet (10 meters) of the Bluetooth device.
Return audio output to iPad. Turn off or unpair the device, turn off Bluetooth in Settings > 
Bluetooth, or use AirPlay   to switch audio output to iPad. See 

 on page 31. Audio output 

returns to iPad if the Bluetooth device moves out of range.
Unpair a device. Go to Settings > Bluetooth, tap   next to the device, then tap “Forget this 
Device.” If you don’t see the Devices list, make sure Bluetooth is on.

Restrictions

You can set restrictions for some apps, and for purchased content. For example, parents can 
restrict explicit music from appearing in playlists, or disallow changes to certain settings. Use 
restrictions to prevent the use of certain apps, the installation of new apps, or changes to 
accounts or the volume limit.
Turn on restrictions. Go to Settings > General > Restrictions, then tap Enable Restrictions. You’ll 
be asked to define a restrictions passcode that’s necessary in order to change the settings you 
make. This can be different than the passcode for unlocking iPad.

If you forget your restrictions passcode, you must restore the iPad software. See 

 on page 129.
