Scan Mode - ARVA Evolution+ Mode D'emploi

In the event of several buried victims . ...

scan mode

Note: This is one of the methods possible for fa-
cing this situation.
Begin by your primary search if necessary...
• In the secondary search phase, if the device detects
a multi-victim situation, the indicator
this means that your device detects several transmis-
sions around you.
• Then continue your search following the standard
method for a single buried victim.
• The device will automatically lock on the device
transmitting the strongest signal, which is theoreti-
cally the victim closest to you. When you have found
the first victim (v1), locate them with your probe and
indicate the position.
Take then one or two steps backwards in the di-
rection you came in. Then switch over to SCAN
MODE:
To switch over to SCAN mode, press several times on
the button 2 (transmission then reception position).
As soon as you are in SCAN mode, the sound cuts
and appears on the LCD screen and flashes for
6 seconds.
DO NOT MOVE YOUR DEVICE, it is scanning the
terrain by a radius of 15 meters around you. Af-
ter its SCAN (cf diagram E), several numerical and
directional indications appear successively on the
LCD screen. Concentrate on the given numbers
and directions (the device will transmit no sound).
Each detected victim is indicated by a distance
and direction.
(The smallest number corresponds to the victim you
have just found v1 and the other number corresponds
to the distance from the victim v2)
The highest indication (and the direction) correspond to
the number of steps you have to take to find victim V2
• Moving in terms of the highest indication, sweep SLOWLY. If you pick up a new signal, follow the standard
search procedure for a single victim from the secondary search phase.
Note: After its SCAN, the device is going to successively repeat 5 times the directions and distance indications
for the detected devices.
After these repeats, it will switch automatically to digital mode.
If while searching for V2, the device brings you back to V1, redo a scan to find the direction of V2 to begin the
above procedure again.
WARNING: Even after having used the SCAN function, a signal can hide another, both having perfectly synchroni-
zed transmissions. SCAN again and check the entire avalanche site.
Note: Think to mark your first signal with a stick or a probe and explore the entire avalanche site... The device
may not display the icon
therefore, do not hesitate to redo a SCAN if any doubt remains and check the ENTIRE area of the avalanche site.
Train yourself!
