When screen lock is enabled, the device requires a PIN number upon waking from sleep mode or when the device is restarted.
To unlock the device:
When the lock screen appears say “UNLOCK”.
Move your head left or right to highlight numbers.
Repeat to enter your entire pin.
The device will go to the Home Screen in the case of a reboot of the device or will return to the last screen open in the case of waking from sleep mode.
