Maintaining the fingerprint reader

Do not scratch the surface of the fingerprint reader with a hard, pointed object, or scrap it with your fingernail
or anything hard. Otherwise, the reader could get damaged.
You might not be able to register or authenticate your finger if:
• The surface of the reader is wet, dirty, or stained.
• Your finger is wet, stained with dirt, mud, or oil, wrinkled, rough, dry, or injured.
• The surface of your finger is different from the one when you enrolled your fingerprint.
• Your finger that you are currently using has not been enrolled before.
To improve the situation, try the following:
• Gently clean the surface of the reader with a dry, soft, lint-free cloth.
• Clean or wipe your hands to remove any excess dirt or moisture from the fingers.
• Enroll and use a different finger for authentication.
