Operating Basics
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.
n
Do not scratch or poke the sensor with your nails or any hard or sharp objects.
n
Do not press the sensor strongly.
n
Do not touch the sensor with a wet finger or any wet objects. Keep sensor
surface dry and free of water vapor.
n
Do not touch the sensor with a soiled finger. Minute foreign particles on a
soiled or dirty finger may scratch the sensor.
n
Do not paste stickers or write on the sensor.
n
Do not touch the sensor with a finger or any object with built-up static
electricity.
Observe the following before you place your finger on the sensor whether for
fingerprint enrollment/registration or recognition.
n
Wash and dry your hands thoroughly.
n
Remove static electricity from your fingers by touching any metal surface.
Static electricity is a common cause of sensor failures, especially when the
weather is dry.
n
Clean the sensor with a lint-free cloth. Do not use detergent to clean the
sensor.
n
Avoid the following finger conditions for enrollment or recognition as they may
result in fingerprint enrollment errors or a drop in the fingerprint recognition
success rate
n
Soaked or swollen finger (e.g. after taking bath)
n
Injured finger
n
Wet finger
n
Soiled or oily finger
n
Extremely dry skin condition on finger
Observe the following to improve the fingerprint recognition success rate.
n
Enroll two or more fingers.
n
Enroll additional fingers if recognition failure occurs often using enrolled
fingers.
n
Check your finger condition. Changed conditions, such as injured, rough,
extremely dry, wet, soiled, dirty, oily, soaked, swollen fingers, may lower the
recognition success rate. Also if the fingerprint is worn down or the finger
becomes thinner or fatter, the recognition success rate may be lowered.
