Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease due to a number of
reasons. To maximize 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 using the fingerprint sensor.
• A fingerprint may not be recognized 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 recognized. Make sure that your finger covers the entire surface
of the Power/Lock key.
• Scan only one finger for each registration. Scanning more than one
finger may affect fingerprint registration and recognition.
• The device may generate static electricity if the surrounding air is dry.
If the surrounding air is dry, avoid scanning fingerprints, or touch a
metallic object, such as coin or key, to remove static electricity before
scanning fingerprints.
