Operating Basics

Observe the following before you place your finger on the sensor whether

for fingerprint enrollment/registration or recognition.

Wash and dry your hands thoroughly.

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.

Clean the sensor with a lint-free cloth. Do not use detergent 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 (e.g. after taking 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 recognition failure occurs often using enrolled

fingers.

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.

The fingerprint for each finger is different and unique. Please ensure

that only the registered or enrolled fingerprint or fingerprints are used

for identification.

Check sliding position and speed (see the drawing below).
