Operating Basics

Failure to follow these guidelines might result in (1) damage to the sensor 

or cause sensor failure, (2) fingerprint recognition problems, or lower 

fingerprint rec-ognition success rate. 

■

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

objects.

■

Do not press too hard on the sensor.

■

Do not touch the sensor with a wet finger or any wet objects. Keep the 

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.

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

■

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

Observe the following to improve the fingerprint recognition success rate.

■

Enroll two or more fingers.

■

Enroll additional fingers if recognition failure occurs often with enrolled 

fingers. 

■

Check your finger condition. Changed conditions, such as injured, 

rough, extremely dry, wet, soiled, dirty, oily, soaked and 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.
