Precautions for fingerprint recognition
Fingerprint recognition accuracy may decrease. To maximise 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 are 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.
• 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 a coin or key before scanning fingerprints to
remove static electricity.
