Join a closed Wi-Fi network: To join a Wi-Fi network that isn’t shown in the list of
scanned networks, choose Wi-Fi > Other, then enter the network name. If the network
requires a password, tap Security, tap the type of security the network uses, and enter
the password.
You must already know the network name, password, and security type to connect to
a closed network.
Some Wi-Fi networks may require you to enter or adjust additional settings, such as a
client ID or static IP address. Ask the network administrator which settings to use.
Adjust settings to connect to a Wi-Fi network: Choose Wi-Fi, then tap next to a
network.
VPN
This setting appears when you have VPN configured on iPod touch, allowing you to
turn VPN on or off. See “Network” on page 117.
Notifications
This setting appears when you’ve installed an application from the App Store that uses
the Apple Push Notification service.
Push notifications are used by applications to alert you of new information, even when
the application isn’t running. Notifications differ depending upon the application, but
may include text or sound alerts, and a numbered badge on the application’s icon on
the Home screen.
You can turn notifications off if you don’t want to be notified or want to conserve
battery life.
Turn all notifications on or off: Tap Notifications and turn notifications on or off.
Turn sounds, alerts, or badges on or off for an application: Tap Notifications, then
choose an application from the list and choose the types of notification you want to
turn on or off.
Brightness
Screen brightness affects battery life. Dim the screen to extend the time before you
need to recharge iPod touch, or use Auto-Brightness.
Adjust the screen brightness: Choose Brightness and drag the slider.
Set whether iPod touch adjusts screen brightness automatically: Choose Brightness
and turn Auto-Brightness on or off. If Auto-Brightness is on, iPod touch adjusts the
screen brightness for current light conditions using the built-in ambient light sensor.
