1. THE FIRST STARTUP 

After the device is connected to power, the white LED flashes 

and the beeper beeps for 1s. When the device is in the stand-

by mode, the white LED is on (waiting for finger identification). 

After each performed operation, the device returns to standby 

mode. 

When the fingerprint database is empty, anybody can 

enrol the first three administrator fingerprints. It is rec-

ommended that you enrol the first three fingerprints 

immediately, so that it is protected from unauthorized 

persons. 

2. PROPER USE 

With the capacitive fingerprint reader of the latest generation 

of Bioreader we provided excellent reading of fingerprints in all 

conditions and minimized the possibility of misuse. However, 

every techno¬logy needs to be used according to its specifica-

tions, and the proper use of the capacitive fingerprint reader is 

described in the following section. With a little practice and by 

following instructions, users will quickly learn to use it correctly. 

The majority of competitors’ products use in-built capacitive 

fingerprint readers over which a finger needs to be swiped. 

Bioreader, on the other hand, has an in-built fingerprint reader 

on which one’s finger is laid/pressed. A great advantage of such 

reader is that one does not need to learn and take care how to 

swipe the finger: one simply lays/presses the finger on the read-

er’s surface. The only thing the user needs to be careful about is 

that the finger is not laid/pressed on the reader with too much 

or too little force, and that finger surface is large enough. When 

you press a finger on the reader, the latter should be covered 

by min. 70% fingertip surface. During identification, the finger 

should not move. It is recommended to enrol min. two fingers 

of each hand, so that in case of injury the user can still open the 

door with a non-injured finger. During enrolment procedure a 

finger should be pressed on the fingerprint reader for 7-10 

seconds. After successful enrolment, the device beeps and the 

green LED flashes for 1 second. 

It is recommended that you enrol the same finger several 

times, so that different positions of a finger are stored in 

the device, thus enabling more successful identification.

 If 

enrolment is not successful (the finger is not correctly pressed 

against the reader or the finger surface is too small), the red LED 

flashes for 1second. The centre of a fingerprint should be in the 

middle of the reader. On this area of a fingertip the number of 

ridges is the highest (top right figure). When using the finger-

print reader, fingers should be normally damp. When fingers 

are extremely dry, the reader will not sense the finger, because 

it also measures electrical conductivity, and with very dry skin 

conductivity is low. Persons with very dry skin can have prob-

lems with finger identification; in this case, frequent use of hand 

cream is recommended. 

Quality fingerprint enrolment is very important: enrol 

your fingerprints with great care!

Individuals with heavily damaged fingerprints or very dry 

skin can considerably alleviate this problem by taking into 

account the following advice:

• 

Carefully enrol your fingerprint; choose the finger with the 

least damaged fingertip and the most prominent ridges. 

• 

When enrolling your fingerprint, the fingerprint reader should 

be entirely or min. 70% covered by your fingertip, and the cen-

tre of the fingerprint should be in the middle of the reader. 

• 

Enrol the same fingerprint several times, 5 times or more, if the 

skin on your fingers is very dry (this usually happens on cold 

days), and take care of normal dampness of fingertip skin. 

• 

Frequently use moisturizing hand cream or damp your fingers 

before you use the fingerprint reader. 

Fingerprint enrol can fail due to several reasons: the fingerprint 

is too small, the finger is wet, extremely dry or dirty (Bioreader 

can read slightly wet or dirty fingers, though; only extremely 

dry fingers can cause problems). 

The time for each function is limited. When enrolling a new 

fingerprint, you have two minutes to conclude the operation.
