• 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.
