The screen is divided into three windows:
SIGNAL LEVEL INDICATOR (Fig.25, item 12);

The INDICATOR window displays the signal level at the marker frequency (Fig. 25, item 7) of
SPECTRUM ANALYZER.
The other two windows (Fig. 25, item 5 and item 8) display the oscillogram and the
spectrogram. Only one window is active at a time, which is highlighted with a white frame (Fig.
25, item 4).
Switching between the OSCILOGRAPH and SPECTRUM ANALYZER windows is carried out using
the
and
buttons. The SETTING "0" function is used to localize the source of the detected
signal.
