Sync with iTunes
Syncing with iTunes copies information from your computer to iPad, and vice versa. You can sync 
by connecting iPad to your computer, or you can set up iTunes to sync wirelessly using Wi-Fi. You 
can set iTunes to sync music, videos, apps, photos, and more. For help syncing iPad, open iTunes 
on your computer, choose Help > iTunes Help, then select Sync your iPod, iPhone, or iPad. iTunes 
is available at 
.
Set up wireless syncing. Connect iPad to your computer. In iTunes on your computer, select your 
iPad, click Summary, then select Sync with this iPad over Wi-Fi.
If Wi-Fi syncing is turned on, iPad syncs when it’s connected to a power source, both iPad and 
your computer are on and connected to the same wireless network, and iTunes is open on 
your computer.
Tips for syncing with iTunes on your computer
Connect iPad to your computer, select it in iTunes, then set options in the different panes.
 
If iPad doesn’t appear in iTunes, make sure you’re using the latest version of iTunes, check that 
the included cable is correctly connected, then try restarting your computer.
 
In the Summary pane, you can set iTunes to sync iPad automatically when it’s attached to your 
computer. To temporarily prevent syncing when you attach the device, hold down Command 
and Option (Mac) or Shift and Control (PC) until you see iPad appear in the iTunes window.
 
If you want to encrypt the information stored on your computer when iTunes makes a backup, 
select “Encrypt iPad backup” in the Summary pane. Encrypted backups are indicated by a lock 
icon  , and a password is required to restore the backup. If you don’t select this option, other 
passwords (such as those for mail accounts) aren’t included in the backup and you’ll have to 
reenter them if you use the backup to restore iPad.
 
In the Info pane, click Advanced to select options that let you replace the information on iPad 
with the information from your computer during the next sync.
 
In the Music pane, you can sync music using your playlists. 
 
In the Photos pane, you can sync photos and videos from a supported app or folder on 
your computer.
 
If you use iCloud to store your contacts, calendars, and bookmarks, don’t also sync them to 
iPad using iTunes.
 
If you turn on iCloud Photo Library, you can’t use iTunes to sync photos and videos to iPad.
Date and time
The date and time are usually set for you based on your location—take a look at the Lock screen 
to see if they’re correct.
Set whether iPad updates the date and time automatically. Go to Settings > General > Date & 
Time, then turn Set Automatically on or off. If you set iPad to update the time automatically, it 
gets the correct time over the network and updates it for the time zone you’re in. Some networks 
don’t support network time, so in some areas iPad may not be able to automatically determine 
the local time.
Set the date and time manually. Go to Settings > General > Date & Time, then turn off Set 
Automatically. 
Set whether iPad shows 24-hour time or 12-hour time. Go to Settings > General > Date & Time, 
then turn 24-Hour Time on or off. (24-Hour Time may not be available in all areas.)
