Operation Manual

Turn Simple Passcode on or o: Choose General > Passcode Lock, then turn Simple
Passcode on or o.
A simple passcode is a four-digit number. To increase security, turn o Simple Passcode
and use a longer passcode with a combination of numbers, letters, punctuation, and
special characters.
Erase data after ten failed passcode attempts: Choose General > Passcode Lock,
enter your passcode, and tap Erase Data to turn it on.
After ten failed passcode attempts, your settings are reset to their defaults and all your
information and media are erased:
 On iPod touch 3rd generation or later: by removing the encryption key to the data
(which is encrypted using 256-bit AES encryption)
 On iPod touch 2nd generation: by overwriting the data
Important: You can’t use iPod touch while data is being overwritten. This can take
up to four hours or more, depending on the model and storage capacity of your
iPod touch. (On iPod touch 3rd generation or later, the encryption key is removed
immediately.)
Restrictions
You can set restrictions for the use of some apps and for iPod content on iPod touch.
For example, parents can restrict explicit music from being seen on playlists, or turn o
YouTube access entirely.
Turn on restrictions:
1 Choose General > Restrictions, then tap Enable Restrictions.
2 Enter a four-digit passcode.
3 Reenter the passcode.
Turn o restrictions: Choose General > Restrictions, then enter the passcode. Tap
Disable Restrictions, then reenter the passcode.
Important: If you forget your passcode, you must restore the iPod touch software from
iTunes. See “Updating and Restoring iPod touch Software” on page 214.
Set app restrictions: Set the restrictions you want by tapping individual controls on
or o. By default, all controls are on (not restricted). Tap an item to turn it o and
restrict its use.
