Acer Iconia B3-A40FHD User Manual - Page 41

Advanced settings - 41 Data Usage (background data) The Data Usage section shows how much data has been transmitted to your tablet, either in total or for each app. This information is useful if you are using a metered service. If an app is using too much data, or you need to control how your data service is used, open the Data Usage menu, and turn Data Saver on. Tap to see a list of apps installed on your device, you may disable background data for individual apps. An app controlled by the Data Saver will only be able to access to a data connection when you're actively using the app. Note Blocking background data may cause some apps to stop working correctly. For example, background data is required to make regular checks for updates, useful for email or messenger apps. More... Putting your tablet in Airplane mode You can enter Airplane mode (also known as 'flight mode') to turn off network and Bluetooth functions and use your tablet during a flight. Check with your airline to confirm which devices are permitted on board. Always follow instructions, such as switching your tablet off during takeoff and landing as it may interfere with aircraft electronic systems. Note When Airplane mode is active, the icon is displayed in the status area. To turn Airplane mode on or off, tap Settings, then under Wireless & Networks tap More > Airplane mode. Alternatively, swipe down from the top of the screen to use the airplane mode tile. Virtual Private Network (VPN) This option enables you to connect to a private network, such as a secure work or office environment.
