as well as due to wear and so
iling in the circulation process.
To adjust the sensor response
level, select the necessary
sensitivity level by shortly
pressing the "Volume"
button. The red light of the
"Volume" button corres
ponds to the highest sensiti
vity level, the yellow one to
the medium level, and the
green one to the lowest le
vel. The device selects the
moderate (yellow) response
level by default.
If the DORS 15 snaps into ac
tion over the bank note area
where there is no magnetic
marks, the note should be tes
ted at the minimum sensitivity
level. If the sensor responds to
nonmagnetic marks or does
not respond to magnetic
marks, then the bank note
may be suspicious and should
be tested for other security
features. If the problem is sol
ved, the genuine bank note
has a polygraphic defect.
The maximum sensitivity le
vel is recommended when
testing the wornout bank
notes with noncontrast
magnetic properties: Russian
roubles, Euro, US dollars, etc.
Note that the magnetic con
trol sensor provides reliable
authentication of the protec
tion elements made by elec
trically conductive materials
(semiconducting as well) and
also by special magnetic ma
terials where ordinary mag
netic detectors do not snap
into action. This property of
the magnetic control sensor
as well as its high sensitivity
should be taken into account
to avoid the false response:
do not touch sensing ele
ments, mechanical parts and
avoid impact on the sensor.
Infrared Control:
1. When using the DORS 15,
any operating mode of
the detector may be selec
ted.
2. To activate the visualizer
(Fig. 4), press and hold
any button.
3. Place the device over the
bank note so that the tes
ted area is located under
the sensor.
4. Select the infrared control
mode by shorttime pres
sing of the "Select" but
ton (IR, the button LED is
red). Moving the sensor
over the tested area, reve
al the locations where the
sensor snaps and does not
snap into action. The snap
2. The tested bank note and
the visualizer should be
placed on a special pad
(supplied with DORS 15).
3. To activate the visualizer
(Fig. 4), press and hold
any button.
4. By short pressing the
"Select" button, select
the magnetic control mo
de (MG, green light is on).
Place the visualizer over
the bank note so that the
tested area is under the
sensor. Moving the sensor
over the tested area, reve
al the places where the
sensor snaps and does not
snap into action. The snap
evidence is a sound signal
and a lit indicator.The
sound signal may be tur
ned on/off by pressing
and holding the "Volume"
button for at least 2 se
conds.

The areas of the sensor
snap are magnetic, of
nonsnap nonmagnetic.
Thus, the magnetic and
nonmagnetic ink distribu
tion over the text and pic
tures may be detected with
high accuracy.
5. Compare the data obtai
ned with the layout of
the magnetic protection
marks for the authentic
bank note.
CAUTION:
Because of the high response
level of the DORS 15 magnet
ic sensor a false response
may occure with a mobile te
lephone working within 2.5
meters round.
6. If the DORS 15 is not used
for an hour, it is automati
cally disabled.
NOTE:
If the test does not provide
high accuracy of the mark
recognition, the sensitivity
level of the sensor should be
adjusted. This is due to large
diversity of the magnetic
parameters for the bank no
tes of various currencies.
Besides, the bank notes of
the same type may vary sig
nificantly from one another
because of technological par
ticularities of manufacturing
