Make sure the power switch (12, Fig. 2) is in the leftmost position (off). Connect the power-and-
control cable plug (8, Fig. 2) to the socket on antenna module (8, Fig. 4). Switch on the device by
turning the knob clockwise; the device status will be displayed on the antenna module as shown
in Table 1 below.

The antenna module is powered
properly.

The battery is discharged and needs
to be replaced.
TUNING

This displays receiver gain. At
startup the gain is automatically set
to maximum, which is signalled by
all the 5 indicator segments being lit.

This displays the operating mode.
The SEARCH mode is selected
automatically at startup.
Upon activation of the device one or more LEDs of the signal level gauge bars (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. Adaptive mode
To activate this mode, press and hold for 3-4 sec the MODE button (2, Fig. 7) on the main unit
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 floor 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.
Meanwhile, 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.
