Make sure the power switch (5, Fig. 6) is in its leftmost position (OFF). Insert the power-and-
control cord plug (3, Fig. 6) into the socket (8, Fig. 4) on the antenna module. Activate the device
by rotating the knob clockwise. The device status will be displayed on the antenna module as
shown in Table 1 below.

POWER red continuous The antenna module is powered
properly.
blinking The battery is discharged and needs
to be replaced.

yellow continuous This displays receiver gain. At
startup the gain is automatically set
to maximum, which is signalled by
all the 5 indicator segments being lit.
SEARCH yellow continuous This displays the operating mode.
The SEARCH mode is selected
automatically at startup.
Upon activation of the device one or more segments of the signal level gauges (1..3, Fig. 4)
may light and go out spontaneously. This would mean that the device should need to be adjusted
to the electromagnetic environment using the adaptive mode.
2.2. Adaptation mode
To activate this mode, press and hold for 3-4 sec the MODE button (1, Fig. 7) on the control
panel. The antenna must be directed away from large metal objects and anything that is presumed
to contain nonlinear elements (it is often best to point the antenna at either the oor or ceiling).
The adaptation takes 10–15 seconds, with all the indicators but TUNING lit in the meantime
on the antenna module. The TUNING indicator will be showing a consecutive lighting of
segments. The user can check if any of the indicator LEDs are dead.
Upon adaptation the device status will be displayed in accordance with Table 1.

may light and go out spontaneously. This would mean that the device should need to be adjusted

2.3. Operational check with test dummies
For that purpose select an area free of responses from nonlinear elements or reecting
surfaces, and place the dummy that is marked red.
Press button (3, Fig. 7) repeatedly to set the receiver gain at 3 lit segments of the
TUNING indicator, which corresponds to medium sensitivity.
Point the antenna at the test dummy and nd the distance at which all the 16 segments of the
INPUT LEVEL Gauge bar 1 light up. For a device that is in proper working order and has self-
tuned properly, this distance should be no less than 0.8 m.
