User Guide
The default setting has been pre-selected. You can adjust the viewing distance
according to your needs.
Note:
1. Ensure the lens of the camera is clearly visible and not covered.
2. Ensure your eyes are clearly visible and not covered.
(The function that detects the distance between the user and monitor
is based on the position of the user’s eyes. Therefore, if the eyes are
covered or there is a strong reflection, distance detection may be
affected.)
Wearing glasses may affect the accuracy of the face image verification.
3. The limits for distance detection by the camera:
Minimum distance: approx. 20 centimters (7.90 inches)
Maximum distance: approx. 70 centimeters (27.55 inches)
Pitch angle (angle of rotation of the face in the vertical plane):
Elevation: 20 degrees
Depression: 30 degrees
Horizontal angle of rotation (angle of rotation of the face in the horizontal
plane): between -20 and +20 degrees
3.3 BackOn Track
BackOn Track lets you easily back up important files to a disc, hard drive, or other
storage device. A Back Up Files project can be scheduled to run daily, weekly, or
monthly. Large backups are automatically spread across as many discs as you
need.
3.3.1 Using BackOn Track
Choose All Programs → Lenovo → FileBackup from the Start menu to launch
the BackOn Track software.
3.3.2 Back up files
Begin by selecting the drive, drive partition, or folder containing the files you want
to back up. You can choose to archive all the files in the selected path or just
certain types of files. You can back up any files that have changed since a specified
date, or create a custom backup based on certain file extensions. Finally, schedule
the project to run on a regular basis, or begin backing up right away.
