Basics 

Return audio output to iPod touch when a Bluetooth headset is connected:  Turn off or unpair 
the device, or turn off Bluetooth in Settings > Bluetooth. Audio output returns to iPod touch 
whenever the device is out of range. You can also use AirPlay   to switch audio output to  
iPod touch. See 

 on page 30.

Note:  The use of certain accessories with iPod touch may affect wireless performance.
Unpair a Bluetooth device:  Go to Settings > Bluetooth and turn on Bluetooth. Tap   next to 
the device name, then tap “Forget this Device.”

After you pair a device with iPod touch, the Bluetooth icon appears in the status bar at the top of 
the screen:

 

•

 or  :  Bluetooth is on and paired with a device. (The color depends on the current color of 

the status bar.)

 

•

:  Bluetooth is on and paired with a device, but the device is out or range or turned off.

 

•

No Bluetooth icon:  Bluetooth is not paired with a device.

File sharing

You can use iTunes to transfer files between iPod touch and your computer. You can also view 
files received as email attachments on iPod touch. See 

 on page 64. If you have the 

same apps that work with iCloud on more than one device, you can use iCloud to automatically 
keep your documents up to date across all your devices. See 

 on page 14.

Transfer files using iTunes:  Connect iPod touch to your computer using the included cable. 
In iTunes on your computer, select iPod touch, then click the Apps button. Use the File Sharing 
section to transfer documents between iPod touch and your computer. Apps that support file 
sharing appear in the File Sharing Apps list in iTunes. To delete a file, select the file in the Files list, 
then press the Delete key.

Security features

Security features help protect the information on iPod touch from being accessed by others.

For security, you can set a passcode that you must enter each time you turn on or wake up 
iPod touch, or when you access the passcode lock settings.

Setting a passcode turns on data protection. Data protection uses your passcode as the key for 
encrypting mail messages and their attachments stored on iPod touch. (Some apps available 
from the App Store may also use data protection.) A notice at the bottom of the Passcode Lock 
screen in Settings shows whether data protection is enabled.
Set a passcode:  Go to Settings > General > Passcode Lock, then tap Turn Passcode On and enter 
a 4-digit passcode.
Use a more secure passcode:  To increase security, turn off Simple Passcode and use a longer 
passcode with a combination of numbers, letters, punctuation, and special characters. 
To unlock iPod touch when it’s protected by a combination passcode, you enter the passcode 
using the keyboard. If you prefer to unlock iPod touch using the numeric keypad, you can set up 
a longer passcode using numbers only.
