To Disable Restrictions, go to Settings > General > Restrictions. Enter your passcode for Restrictions (this should be different to the iPad passcode). Once you have entered your passcode, you will see the option to Disable Restrictions at the top of the screen.
You will then be prompted to enter your passcode for Restrictions and this will then disable all restrictions from the iPad.
Disabling these restrictions will NOT change the restrictions enforced by the RGS Airwatch System. For further information on restrictions, please click here.
