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. 
❑ 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 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 elec-

tricity.

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 sen-

sor.

❑ Avoid the following finger conditions for enrollment or recognition as they 

may result in fingerprint enrollment errors or a drop in the fingerprint recog-
nition 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
