available, except for switching to the Main Menu of the device (by pressing "MODE").
3.2. DIFFERENTIAL MODE
In the DIFFERENTIAL mode, signal levels registered during previous scanning cycles in the
"PANORAMA" mode, are set as "0", and only signals in excess of "0" will be shown on the screen
(differential spectrum).
The DIFFERENTIAL mode can be used for isolating the signals from sources within the
inspected premises, from external signals.
The DIFFERENTIAL mode can be activated from the "PANORAMA" mode (fig.9) by pressing
"F3". The "F3" key field will become highlighted.
Upon activating the DIFFERENTIAL mode, the screen will look as shown in fig.11.
