14. Secondary Search Phase
14.1 Digital Search Mode
The digital search mode offers the user
optical guidance.
At distances above 40 meters the display
prompts you by means of the lightning arrow
to apply one of the “Primary Search Phase”
strategies:
Even in this early phase, a well-trained
rescuer may shorten the search path with
the aid of the analog tones or recognize a
multiple burial situation through the typical
dual tones.
If the
distance to the victim is less
than 40 meters, the distance and the
direction are given.
The microprocessor automatically adjusts
the sensitivity of the receiver for optimum
detection of the received signals.
This search mode requires less training and
makes it easier to locate a victim. Due to the
laws of physics, it is not possible to deter-
mine the distance with absolute precision.
The figures shown are only to be interpreted
as relative.
Focus is therefore on the
tendency, to increase or decrease and
not the absolute values.
Due to the
changing shape of the flux lines in the
immediate vicinity of a victim, the direction
display is suppressed at distances below
3 meters. The pinpoint location is done by
means of the
distance display only.
The digital search
mode requires less
training and makes it
easier to locate
a victim.
●
Hold the Barryvox
horizontally
in front of you.
●
Watch the distance and direction
information on the display.
●
Move in the indicated direction.
●
If the
distance decreases,
you are
getting closer
to the victim.
●
If the
distance increases
, you are
moving away
from the victim.
Continue the search in the
opposite
direction.
Important points to be noted
when using the digital search mode:
