Operating Basics
■ Clean the sensor with a lint-free cloth - do not use detergent or any 
other chemicals to clean the sensor.
■ 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
■ Soaked or swollen finger, for example as may occur after taking a 
bath.
■ Injured finger
■ Wet finger
■ Soiled or oily finger
■ Extremely dry skin condition on finger
Observe the following to improve the fingerprint recognition success rate.
■ Enroll two or more fingers.
■ Enroll additional fingers if a recognition failure often occurs when using 
already enrolled fingers.
■ Check the condition of your finger - any conditions which have changed 
since enrollment, such as injury, rough skin, and extremely dry, wet, 
soiled, dirty, oily, soaked or 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.
■ As the fingerprint for each finger is different and unique you should 
ensure that only the registered or enrolled fingerprint or fingerprints are 
used for identification.
■ Check the position and speed at which you swipe your finger across the 
sensor - please refer to the preceding drawing.
■ The fingerprint sensor compares and analyzes the unique 
characteristics in a fingerprint. However, there may be instances where 
certain users are unable to register their fingerprints due to insufficient 
unique characteristics in their fingerprints.
■ The recognition success rate may differ from user to user.
