A user's manual for the iPad 2 is available on Apple's website at Support.Apple.com. Apple has titled the manual for the iPad 2 "iPad User Guide for iOS 4.3," as iOS 4.3 was the operating system in use at the time of the iPad 2's release in 2011.
Apple has released several generations of the iPad. An iPad 2 can run on Apple's latest operating software, iOS8, as of April 2015. The user guide for the iPad 2 became available in March 2011, and it covers how to use all of its features. The Apple user guide for its latest iOS system may also be useful for anyone using an older iPad with the newest iOS.
