Scanning your finger
To scan your finger, tap the fingerprint reader with the top joint of your finger and hold your finger there for
one or two seconds with a little pressure. Then lift the finger to complete one scan.
Maintaining the fingerprint reader
The following actions could damage the fingerprint reader or cause it not to work correctly:
• Scratching the surface of the reader with a hard, pointed object
• Scraping the surface of the reader with your fingernail or anything hard
• Using or touching the reader with a dirty finger
If you notice any of the following conditions, gently clean the surface of the reader with a dry, soft, lint-free
cloth:
• The surface of the reader is dirty or stained.
• The surface of the reader is wet.
• The reader often fails to enroll or authenticate your fingerprint.
If your finger has any of the following conditions, you might not be able to register or authenticate it:
• Your finger is wrinkled.
• Your finger is rough, dry, or injured.
• Your finger is stained with dirt, mud, or oil.
• The surface of your finger is different from the one when you enrolled your fingerprint.
• Your finger is wet.
• Your finger that you are currently using has not been enrolled before.
To improve the situation, try the following:
• Clean or wipe your hands to remove any excess dirt or moisture from the fingers.
• Enroll and use a different finger for authentication.
