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.
Ţ 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.
Ţ 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.
Ţ 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.
Ţ 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.
Ţ Scan only one finger for each registration. Scanning more than one
finger may affect fingerprint registration and recognition.
Ţ 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.
