Figure 4-2 Slide the finger over the recognition sensor

■Avoid swiping with the finger stiff or pressed-on too hard:

Fingerprint reading may fail if the center of the fingerprint is not touching on the sensor, or when finger is swiped while pressing hard. Make sure that the center of the fingerprint is touching the sensor before swiping.

■Confirm the center of the fingerprint whirl before swiping:

The thumb’s fingerprint has a bigger whirl, which is prone to misalignment and distortions. This will cause difficulty in registration and a drop in the authentication success rate. Always confirm the center of the fingerprint whirl so that it is swiped along the centerline of the sensor.

■When fingerprint reading is not successful:

There is a possibility of authentication failures if the finger is swiped too quickly or too slowly. Follow the onscreen instructions to adjust the speed of the swipe.

Points to note about the fingerprint sensor

Failure to follow these guidelines might result in (1) damage to the sensor or cause sensor failure, (2) finger recognition problems, or lower finger recognition success rate.

■Do not scratch or poke the sensor with your nails or any hard or sharp objects.

■Do not press the sensor strongly.

■Do not touch the sensor with a wet finger or any wet objects. Keep sensor surface dry and free of water vapor.

■Do not touch the sensor with a soiled finger. Minute foreign particles on a soiled or dirty finger may scratch the sensor.

■Do not paste stickers or write on the sensor.

■Do not touch the sensor with a finger or any object with built-up static electricity.
