If the Manual is failing to display, try closing the app fully from the multitasking area and then opening it again. However, this is an indication memory may be becoming fragmented and we recommend to reboot the device.
To turn the device off: Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
To turn it on again: Press and hold the Sleep/Wake button until the Apple logo appears. It will then boot up in a few seconds.
