Precautions on Using Fingerprint Authentication
❑
The fingerprint authentication technology does not ensure complete user authentication or complete protection of your
data and hardware.
Sony assumes no liability for any problems and damages arising out of your use of or inability to use the fingerprint sensor.
❑
The fingerprint recognition rate depends on your operating conditions and varies among individuals as well.
❑
Be sure to make a backup copy of the data stored on the built-in storage device, especially in the encrypted archives
created with the
File Safe feature, before sending your computer for repair.
Sony assumes no liability for any loss or modification of your data that might have occurred during the course of repair.
❑
In case the built-in storage device has to be initialized, for example after the repair work, the fingerprint templates will be
lost. You will have to register them all over again.
❑
The maintenance and management of data concerning fingerprint authentication must be carried out at your own risk.
Sony assumes no liability for any defects arising out of your data maintenance and management.
❑
Before disposing of your computer or transferring it to a third person, it is strongly recommended you erase the fingerprint
data registered on the fingerprint sensor after erasing the data stored on your built-in storage device. See
Erasing the
Registered Fingerprints (page 134) for the detailed procedure.
❑
A fingerprint sensor may malfunction or be damaged if you scratch its surface with:
❑
a solid or sharp-pointed object
❑
fine objects, for example swiping a finger covered with dirt across the fingerprint sensor
❑
Discharge static electricity from your finger by touching a metallic object especially during dry seasons (e.g. winter) before
scanning your fingerprint. Static electricity may cause the fingerprint sensor to malfunction.
