SECTION 4: OPERATION INSTRUCTIONS
1. Fingerprint Management
1.1 Registration of fingers:
You can register 80 fingers at most, including 5 managers and 75 common users.
5 managers can not only control the lock functions (e.g. unlock), but also the
fingerprint management (e.g. register, delete fingerprint); while 75 common
users can only operate the lock and they are not authorized to manage fingers.
ATTENTION: As the default setting, there is not any finger in the lock before it
is in use, so any finger can open it when it is electrified. Therefore, make sure
to register the fingers as soon as possible to ensure safety.
1.1.1. Registration of manager (1 ~ 5)
STEP After the lock is electrified, press button to start. The collecting window turns
bright and the green light glitters.
STEP Press button down and dont release the finger until 10 seconds pass. (The
red light glitters once after 5 seconds and it will glitter twice in all, with a di sound at the
same time. After the red light glitters twice, release your finger. The collecting window is
bright and the green light and red light glitter together).
STEP (If there is no registered finger in the lock, go straight to the next step.) The manager
presses his registered finger once to confirm. If it succeeds, there will be 3 continuous di
sounds and the green light glitters; if it fails, the red light turns bright and a di sound is
emitted to remind you of inputting correct manager finger.
STEP After confirmation, input finger needed to be registered, input each finger for 3
times. (The collecting window will be dark after you press finger each time to remind you of
releasing finger. After hearing the di sound, input the same finger again. 3 times in all).
STEP After 3 times input, three di sounds are emitted to remind you of registration are
complete. You can continue to input other managers (repeat the former procedure) or wait to
do other operations after the collecting window is dark. If the input fails, a di sound is given
and the red light turns bright to remind you of registering fingers again (repeat the last step).
NOTE: It is recommended to register not less than 2 managers for the convenience.

SECTION 8: ATTENTIONS
FINKIN Fingerprint locking devices are used by people with the need for a more
secure working environment. To ensure a long lasting trouble free use of this
product, please read the following cautions. Keep away from:
Strong magnetism
Strong radiation
Salt
Dampness
High temperature
Low temperature
Direct sunshine
1. FINKIN locking devices retain many characteristics of fingerprints. There
are no pictures of them, so there is not a privacy problem.
2. When used, your finger must not be too dry or too damp. If your finger is too
dry, simply touch your forehead or nose to make a primary contact.
3. Be careful to not scratch the fingerprint scanning window. Please keep the
window clean by using a soft damp cloth. Do not use any type of abrasive
cleaners as they will damage the scanning window.
4. If the door is distorted or becomes warped, it will cause too much friction
between the lock bolt trough and dead bolt case. So the locking device works
properly, you will need to adjust the position of the lock trough and the dead
bolt case.
5. Beeping alarm will sound when battery is low on power, change to a new
www.chinus.net CHINUS TECHNOLOGY
Page 13
battery.
6. Key can open door at any status.
7. For security, every user should use more than two fingerprints.
8. If there are complications on opening the door lock, contact the local
distributor for assistance. Do not try to repair the fingerprint lock assembly.
SECTION 9: FAQs
QUESTION: Fingerprint lock works with batteries, so what should we do if the batteries fail?
ANSWER: The lock is supplied by four AA alkaline batteries. The door lock alarm will sound
automatically. Replace the old battery with new batteries. When the alarm is first sounds, you can
use the door lock approximately 30 more times. You can have access through the door by key if
necessary.
QUESTION: My finger was injured or cut, how can I open the door?
ANSWER: Normally small cuts will not restrict access, larger cuts will require you gain entrance
with your passage key.
QUESTION: Why is it necessary to input my fingerprint three times during programming of the
lock mechanism?
ANSWER: On registering the finger, our model needs 3 times to collect the fingerprint
characteristics to ensure their accuracy, while when we open it, our model just compares the image
with the collected characteristic. Therefore, once is enough.
QUESTION: Why does the door not unlock with my registered finger?
ANSWER: There are four basic reasons for this:
a) The fingerprint used is not the finger recorded.
b) Your fingerprint could be too dry or too damp.
c) Finger was not pressed firmly enough on the scanning window, use additional pressure..
d) The original fingerprint was not imprinted in the memory firmly enough and the system cannot
identify it. It is best to use two fingerprints when programming, so there would be a back up.
Re-program your fingerprint lock with new use prints.
QUESTION: After I press button and press button for a few seconds, why cant I
get into the process of fingerprint deletion?
ANSWER: Before you press button , you may touch this button for a short time carelessly.
In such a situation, the system needs passwords to continue. Therefore, you have to wait 9 seconds
until the light extinguishes. If you want to delete fingerprints, please press button directly for
5 or 10 seconds after operation starts.
