Checklist before reporting a failure
Category Problem Solution
Power
The power is being supplied
but the device does not
operate.
• If the terminal and the bracket are far away from each other, the device
may not operate due to the temper switch.
• Check the adaptor or the power cable.
PIN
I lost my PIN.
• For a normal user PIN, request it from the administrator and enter it again.
• If you have lost the Admin PIN, contact the installation company.
I entered my PIN and pressed
the OK button, but I still
cannot open the door.
• Check if you have entered the registered PIN correctly.
• Check if you have changed the PIN recently.
• If you cannot remember the PIN, request it from the administrator and
enter it again.
Fingerprint
The fingerprint has been
enrolled but fingerprint
authentication cannot be done
smoothly and errors occur
frequently.
• Check ‘How to enroll a fingerprint correctly’ and enroll the fingerprint
again.
• If your fingerprint has a cut, the device may recognize your fingerprint as
someone else's fingerprint.
• If there are a large number of enrolled fingerprints, change Matching
Timeout and try again.
• The authentication rate may vary for each fingerprint due to different
characteristics. Enroll the fingerprint of another finger.
Suddenly fingerprint
authentication cannot be
done.
• Check if the finger or the fingerprint sensor is smeared with sweat, water
or dust, and wipe the finger or the fingerprint sensor clean.
• Wipe your finger and the fingerprint sensor with a dry towel and then try
again.
• If the fingerprint of your finger is too dry, blow on the fingerprint and then
try again.
Door Lock
The door cannot be locked
when I close the door.
• The electric lock may be malfunctioning. Have an inspection through the
installation company.
Time
Suddenly the time has
become incorrect.
• BioLite N2 is equipped with a built-in battery, but if power is not supplied
for an extended period of time, the built-in battery may die, causing the
time to become incorrect. For information on correcting the time, referring
to Date & Time.
Admin
Access
I lost my Admin PIN, so I
cannot access the Admin
mode.
• Because the administrator grants an access permission in BioLite N2,
only the administrator can access the Admin menu.
• If you need to access the Admin menu, you can issue a PIN through a
required procedure. Ask the installation company for the procedure to
issue the password.
