Guide the detector over a location on the
surface to be examined, where you know that
there is no object, which you are looking for.
Then press the PUSH button
5
and keep it
pressed down. A tick symbol
13
will be flash-
ing on the right side top corner of the display
2
to indicate the calibration is on going.
Wait for a while for the calibration process to
complete. The completion of the calibration
will be indicated by a short double signal
tone and the tick symbol
13
on the display
2
will stop flashing. Now, guide the detec-
tor, over the surface to be examined. It is pos-
sible that during this some short signal tones
may sound. These are however without any
meaning, so long as no intensity display
11
appears in the detector display.
If there is an object, for which the search is
activated, in the vicinity of the detector,
several bars appear at first on the intensity
display. As proximity to the search object in-
creases, the number of bars increases on the
intensity display (Fig. C).
If the detector is exactly over the search
object, a continuous signal tone sounds.
In the case of a search for a power line, the
voltage sign ( )
10
also appears in addition
to the intensity display. Please use the pencil
4
for marking the positions.
Always guide the detector in a straight line
in all the searches. To locate the object more
precisely, guide the detector over the surface
to be examined in a forward direction for
both Metal and Wooden beam search. For
the Void search, the detector can be guided
in both forward and backward directions. For
