9-10-2 Operating procedure in Sound mode

This mode searches for a bugging device and determines an approximate
9
distance to it by producing a sound from the DJ-X11 to make the bugging
device emit the sound and measuring the time difference between when
the DJ-X11 produces the sound and when it receives the signal of the
sound. The advantage is that when the receiver determines the presence
of a bugging device, it provides a notifi cation of the approximate distance
to the device with a sound and on the display. The receiver emits a
continuous loud beep during the search.
If you want to use Sound mode alone, set the "Bug coupling" option for
the mode coupling setting of the Bug Detector function to "OFF".
Hold down the left dial (approx.
1
one second) to activate the
Sound mode.
Scanning starts automatically.
The receiver emits a continuous beep
during scanning.
When no bugging device is found after the specifi ed range is scanned for a
certain period of time, "Stop" is displayed on the LCD and the search fi nishes.

When the receiver determines the presence of a bugging device, it produces
shorter beeps.
When the receiver gets closer to the bugging device, the intervals between the icons
and beeps become shorter; when the receiver moves away from the bugging device,
the intervals between the icons and beeps become longer. The function pauses when

ever, a bugging device is actually present, you can judge this from the
fact that the howling noise is always part of the ambient sound.
