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.

• 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 before scanning fingerprints to

remove static electricity.
