General information
General infor mation
Preface
These operating instructions will enable you, as the operator, to
operate the eqo system as intended.
These operating instructions do not, however, deal with the
detection of objects in millimetre-wave images.
Using the functions of your eqo effectively and being able to detect
threats requires a certain degree of expertise. It is possible to
acquire these skills by attending an eqo operator training session.
It is recommended that you read these instructions carefully prior
to using your eqo. In particular, please be sure to read the section
entitled "Safety instructions", which contains important
information concerning your safety.

General information
About these operating instructions
Place to keep the docu m e ntation
These operating instructions along with the referenced product
documents (min. 1 copy of each) should be stored next to the
operator’s workplace. This is to ensure that the operator can
access at any time the information he requires to perform her/his
work.
Classification of the safety instructions
Danger categories
The safety instructions in this manual are subdivided into three
danger categories. These categories differ with regard to the
severity of injuries that can result from the non-compliance with
the instructions:
D A N G E R
Indicates a directly threatening danger. Non-compliance
leads to the most severe injuries or death!
W A R NI N G
Indicates a possibly dangerous situation. Non-
compliance can lead to the most severe injuries or
death!
C A U TIO N
Indicates a possibly dangerous situation. Non-
compliance can lead to slight or minor injuries!

Product Description
Product D escription
eqo has been developed to enhance the capability of security
screening personnel by enabling the detection of weapons,
explosives, or contraband hidden under clothing using millimetre-
wave technology.
The person to be screened stands with arms raised in the
screening area of eqo and turns through 360°. All objects located in
the screening area are scanned by means of millimetre-waves. The
system then processes this data. A two-dimensional image of the
person in the screening area is displayed on the local operator
station.
The system consists of three main modules (see Fig. 1), the local
operator station 1, the flat scanning panel 2, and an entrance
arch 3 containing the transceiver, digital receiver and the power
supply. The arch is attached at right-angles to the end of the flat
scanning panel.
Two different variants exist, a left-hand and a right-hand version.
The variants differ in the position of the flat scanning panel 2
which can be attached on either side of to the power supply pillar
4. Fig. 1 shows the right-hand version of the eqo, Fig. 2 the left-
hand version. The right-hand version is defined as the
configuration where the flat scanning panel is on the right-hand
side of the person who will be scanned as they enter the system
through the arch, and vice-versa for the left hand version.
Furthermore, the local operator station can be placed at two
different positions, either next to the flat scanning panel (see Fig.
3) or next to the arch.

Operation
Stop image capture
Press t to stop image capture. Image capture will also stop
after the maximum scanning time of 30 seconds has elapsed.
However this does not actually end the screening process. You
can continue to review previously tagged areas using the control
keys (F 13) and the function keys (F 11).
If no threat is detected, the person who has been scanned can
then be told that they are free to proceed.
In the case where a potential threat object has been identified,
any site specific standard operating procedure (SOP) should be
followed. For example a targeted pat-down should be
performed as indicated by the position of the threat on the
image.
Finish the screening process
Press the Finish key on the function key panel to end the
screening process.
This will clear the person displayed in the viewing window and
reset the timeline. Once the priority keys r and s are
available the system is ready to start a new screening process.

Daily Test Procedure
Test card
After starting eqo each morning, the operator is advised to perform
a test card scan. This is done using a specifically designed test card
(see Fig. 27). The card is manufactured from a plastic material
which is transparent to millimetre waves. Metal strips of different
widths are attached to the surface of the card. The number next to
each section signifies the width of each strip in that section and the
gap between adjacent metal strips.
During the test the operator holds the card vertically in front of the
system (i.e. in the orientation shown in Fig. 27), in the centre of the
scan volume (this is identified by the centre of the symbol on the
floor mat), at a height of approx. 1.5 m from the floor to the top of
the test card.
It is expected that at the centre of the scan volume, a properly
setup imager will be able to resolve lines (horizontal or vertical) of
6mm width. The results of the test will be different depending on
the distance from the panel and the location in the scanned
volume. Moving the test card closer to the panel should result in
the resolution of lines down to 4mm.
Important!
The card may need to be rotated in the vertical plane
(max. 10 degrees) to achieve optimum results.
The test procedure is as follows:
Start the system according to the procedure outlined in the
operator manual.
Allow the system to run for a minimum of 5 minutes after log on
- make sure there are no objects in the scan volume during this
time.
Rotate or tilt the card to achieve best image, as described
above.
Review the image after the test using and keys.
Make sure the number of lines on the image corresponds to the
number of lines in the test card.
