First Start Up; Proper Use; Power Mode - Navkom Biohandle User Manual

1. FIRST START UP

After the device is connected to power, the blue and red LED
will flash and the buzzer will buzz simultaneously for a short
period. After this period, the blue LED will start to shine con-
tinuously which indicates that Biohandle is ready to be used. If
power save mode is on, blue LED shines only 15 s after pressing
any button and 15 s after each operation is completed. This also
indicates that the device is in freescan mode (is waiting for a
fingerprint). After performing any of the functions it also returns
to the freescan mode. If device is in sleep mode (power save
mode), all functions and LEDs are switched off. Device can be
activated with pressing on any button for 1 s.
When fingerprint data base is empty, anyone can enrol
fingers, so it is recommended that first three admini-
strative fingers are enrolled immediately!

2. PROPER USE

The capacitive area sensor used in the Biohandle enables excel-
lent fingerprint scanning in any conditions and simultaneously
minimizes chances of misuse. Nevertheless, every technology
needs to be used according to its specifications, so the correct
usage of the capacitive area sensor is described in the following
section. With a little practice, users will quickly learn to use it
correctly. Most of competitive products are using swipe capa-
citive sensors. Big advantage of capacitive area sensor is, that
users don't need to learn how to swipe. Finger should be simply
touched to the sensor. The only thing that a user should take
care of, is that finger is not pressed too hard or too soft, so the
area of finger touching the sensor is big enough and centered,
like it is shown on the picture. Also when finger is being scan-
ned it should not move. It is recommended to enrol at least 2
fingers from each hand, so that in case of injury user can still
open the door with the finger which is not injured.
During enrolment procedure, finger must be pressed for 7-10
seconds (pic. 1).
Fingerprint core should be placed at the centre of the sensor
(fingerprint core has max. Biodata info, pic. 2). If image enrol is
not successful (finger was pressed too hard/too soft or sensor
area coverage is too small) red LED will flash one time for 1 s.
It is very important to make a good enrolment and to
store the finger in high quality!
THE CENTRE
IMPORTANT:
It is necessary to perform a good scan when finger is being
enrolled. This enables the device to get the best image possible
and, in doing so, drastically reduces the possibility of subsequ-
ent unsuccessful identification. It can happen that finger enrol-
ment won't be successful. This can happen for various reasons:
The fingerprint image was too small, the finger was wet or dirty
(Biohandle can usually identify a fingerprint even with wet and
greasy fingers but in the enrolment phase it is best to have
clean hands). Every function is limited by a time out. When a
new finger is being enrolled one has 2 minutes to complete the
enrolment. Even if the function wasn't concluded for some rea-
son, there is no fear of misuse. The same finger can be enrolled
more than once. This is an advantage for the people with da-
maged fingerprints. To store the finger more than once decre-
ases the possibility of recognition failure. It is recommended
that administrator fills the Administrator and user list, which is
enclosed to this manual, so that there is a complete overview
who is administrator, who are users, when they were enrolled or
deleted and which fingers are enrolled.

3. POWER MODE

Biohandle has two kind of power modes. When power save
mode is active, the device turns off 15 s after each operation
is completed. Wake up can be performed by pressing on any
button for 1 s, device will be ready to use in 0,4 s. After wake up,
device is in freescan mode (is waiting for a fingerprint) for 15
