To lock the device, tap Device unlocked in the Today screen. The Today screen shows

handheld is unlocked. The exceptions are the

always respond when pressed.
Communication with external devices such as a GPS receiver, or external sensors used
by GPS field software, is not interrupted by locking the handheld. This means that you

could lock the device so that you can safely transport it between features, while
keeping the software connected to the GPS receiver so that you can continue recording
GPS positions.
To unlock the device, tap the Unlock notification in the left corner of the Today screen
menu bar and then tap
Unlock.
You can help to keep your data secure by requiring a password each time the handheld
is turned on. Tap / Settings / Personal / Lock to set a password or to change
password settings.
