shall be used for a visual detection of authenticity of banknotes, securities, ex-
cise stamps and other documents with the protective marks that may be verified
by the device.
THE DEVICE IS EQUIPPED WITH
■ an ultra-violet (hereafter – UV) source consisting of 3 fluorescent lamps
(6W each);
■ a top infrared (hereafter – IR) source emitting at the 850 nm and 940 nm
wavelength;
■ top white oblique source with an opportunity to examine a variable
color inks (OVI);
-
■ a viewing table with combined illumination – transmitted IR light and white
light;
* provided the detector is used in strict compliance with the given User Manual and the
applicable technical standards.
5
■ 7” color TFT LCD;
■ two video cameras transmitting image of the banknote (document) on
the viewing table to the LCD screen in scale 1:1 or with 10-fold magnifi-
cation;
■ the connectors for video magnifier DoRs 1020, and a detector of magne-
tic and IR marks DORS 15;
■ an additional video input and a video output.
THE DEVICE MAY
1. Verify absence of a general visible luminescence in ultraviolet light on
a banknote (document).
2. Verify a presence of IR marks in a reflected and transmitted light as well
as verify IR blink marks in two-wave lengths mode (940/850 nm).
3. Verify a luminescence of the specific areas of a banknote (document) in
UV light (marks, security threads and fibers).
4. Verify watermarks and security threads on banknote (document).
5. Examine the surface of banknotes or documents with protection
elements in a white oblique reflected light. This way you can verify the
relief of printed elements, a tilting effect and the marks made with
variable color inks.
6. Verify an authenticity of micro perforations.
7. Verify the security elements on a banknote that are printed with a variable
color ink (OVI).

8. Perform an advanced verification under a 10-fold magnification
in two b ands (white/IR) when using a built-in 10x camera or and in
three band s(white/IR/UV) when using th e vide o magnifier. DORS 1020
This way you can verify a coincidence of thin multicolored lines of the
currency design, a readability of a microtext and the currency design at
specific points.
9. Verify a presence of magnetic marks when using the DORS 15
detector of magnetic and IR marks.
The UV marks may be examined on the surface of the document when it is
put on the viewing table of the device. The IR marks and IR blink marks can
be examined on the 7” LCD o f the device. When the IR – marks are being
inspected on the display, a 10-fold zoom mode makes it possible to check the
structure of the mark lines without the video magnifier.
The device has an additional video input that makes it possible to display
animage from an external video signal source, for example, from a CCTV
camera. The video output may be used for transmitting the image to an
external display or a co mputer.

The device is controlled with an on-screen menu system. There are special
buttons for the most frequently used functions. The device may be used by a
cashier who had training in a visual detection of authenticity of banknotes
after he has studied the given manual.

VERIFYING IR BLINK MARKS
Place a banknote or a document on the device viewing table. The docu-
ment inside the device shall void direct sunlight or the light from
powerful incandescent lamps. Otherwise inspection of the mark will be
diffi cult or absolutely impossible. Choose built-in camera with no

marks mode by pressing the IR key () – the “IR Blink” message shall
be displayed. If it is required, adjust the required brightness and contrast
of the image on the display. The IR blink marks should clearly blink with
an interval of about 2 times per second. A repeated pressing of the
IR key (message “IR” shall be displayed) switches off the mode.
REFLECTED LIGHT CONTROL
You can use a source of top white light or a source of oblique white light for
the reflected light control.
Place a banknote or a document on the viewing table of the detector.
Use DL key () for switching on a source of top white light (a message
“TOP WHITE” is appeared on the screen) or a source of oblique white
light (a message “oblique white” is appeared on the screen). Examine a
banknote (or a document).
These modes are ideal for control of such security features as color variable
inks and latent images. Besides that, you can evaluate a height of printed
elements, since high elements are produced remarkable shadows under
oblique light.
The detector is used LEDs of high brightness as sources of white light,
therefore WE STRONGLY SUGGEST YOU DO NOT LOOK AT SOURCES
OF WHITE LIGHT.
VERIFYING MARKS, PRINTED BY OPTICAL VARIABLE INKS (OVI)
Place a banknote or a document on the device viewing table. To obtain the
most obvious change in color, the banknote shall be either in the middle of
the viewing table or closer to its back edge. Press the DL key () to switch
on the mode of a variable color ink inspection (message “Variable color”
will be displayed). Monitor the color of the marks printed in a variable color
