Enter and confirm your passcode
Prepare the App:
Return to the Home screen and open the app you want to look the iPad on
Start Guided Access:
Triple-click the Sleep/Side (or Top) button
Enter you Guided Access passcode when prompted
Configure Disabled Areas (Optional)
Select or drag over any areas of the screen you want to disable
Tap 'Continue' to activate Guided Access
The iPad should now be locked in the selected app and ready for use!
