ARVA 3 Axes Modo De Empleo página 12

Situations with two
N.B: This is one possible method for finding victims. The
user may decide to stay in Advanced mode for the entire
search and adjust the sensitivity level with the + and -
buttons to isolate signals from different victims
■ Start with the initial search if necessary, in either Stan-
dard (numerical) mode or Advanced (analogue) mode.
In the secondary search phase, if indicator
means that the ARVA is picking up several signals around
you, mark the area with a ski or pole (F2).
In standard mode, the ARVA will automatically lock on to
the unit emitting the strongest signal, which is theoreti-
cally the victim closest to you. Once you have found the
first victim (F3/v1), locate him using your snow probe and
mark the location
■ Return to the point that you marked earlier and switch
the ARVA to Advanced (Analogue) mode (F4): the unit will
indicate the various signals it has picked up.
Several estimated distances are displayed, along with va-
rious levels of sound depending on how close they are.
N.B As soon as you switch to Advanced mode, the unit
will automatically revert to sensitivity level 9 (maximum
range). Use the - button to lower the level and search for
the second victim.
■ When you pick up the signal from the second victim, two
estimated distances will be displayed on the LCD screen.
To obtain a closer estimate, reduce the sensitivity until the
victim's signal is barely audible and focus on the higher
figure (the lower figure with a strong signal corresponds
to the first victim v1 and the weaker signal to the distance
of victim v2).
Determine the direction to follow by sweeping the ARVA
from right to left and attempting to reduce the distance of the higher figure. Once you have found the right direction,
move forward, taking the number of steps indicated.
One of the figures will increase and the other decrease, while at the same time one of the signals will increase and
the other decrease.
When you have taken the number of steps indicated, switch to Standard (numerical) mode (F5). Make a SLOW sweep
with the unit. The ARVA will automatically lock on to the closest victim, i.e. the second one. Repeat the standard mode
search, as in the case of a single victim. If you return towards the first victim, go back to the starting point (where you
obtained the multiple victim signal) and try to find the direction for the second victim in Advanced mode.
N.B. In the case of multiple victims, it is advisable to use an earphone to distinguish the various signals more clearly.
