User's Manual
Avoid swiping with your finger stiff or pressed too hard onto the sensor,
and take care to ensure that the center of the fingerprint is touching the
sensor before swiping. Either of these conditions may cause fingerprint
reading to fail.
Check the center of the fingerprint whirl before swiping and then
ensure this is swiped along the center line of the sensor.
There is a possibility of authentication failures if the finger is swiped too
quickly or too slowly - follow any on-screen instructions to adjust the
speed used during the swipe process.
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 the
sensor surface dry and free from water vapor.
Do not touch the sensor with a soiled or dirty finger as minute foreign
particles of dust and dirt may scratch it.
Do not paste stickers or write on the sensor.
