Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease due to a number of
reasons. To maximise the recognition accuracy, check the following before
using the device.
•
The device’s Power/Lock key has a fingerprint sensor. Ensure that the
Power/Lock key is not damaged by a metallic object, such as coin or
key.
•
When water, dust or other foreign substance is on the Power/Lock key
or your finger, the fingerprint registration or recognition may not work.
Clean and dry your finger before having the fingerprint recognised.
•
A fingerprint may not be recognised properly if the surface of your
finger has a scar or is not smooth due to being soaked in water.
•
If you bend your finger or use the fingertip only, your fingerprint may
not be recognised. Make sure that your finger covers the entire surface
of the Power/Lock key.
