blocking function (masking) of the victim in the vicinity
Note: This method is one of the options for resolving the
situation.
Begin your primary search if necessary...
- In the secondary search phase, if the device detects a
multi-victim situation, the lamp
your device has detected several transmitters around
you.
- Then continue your search, following the standard
method for a single buried victim.
- The device will automatically lock onto the device emit-
ting the signal which is the strongest, and therefore theo-
retically the victim closest to you. You have found the
first victim (v1); locate the person with your avalanche
probe and mark how they lie.
You can therefore switch the device to the BLOCKING
function. In order to switch the device, quickly activate
selector into the emitting position followed by the re-
2
ceiving position. As soon as you are in BLOCKING mode,
the sound cuts out and only CE appears on the screen for
3 seconds. The device's software 'blocks' the signal in
the vicinity (that of the victim discovered) and gives you
the next signal received with a distance and direction.
Example:
• Having located victim V1, the device indicates via pic-
togram that a multiple burial scenario is present.
• Remain level with the discovered victim V1 and quickly
activate the emitting/receiving selector. You are then
in BLOCKING mode. The device continuously displays
CE for 3s and then gives you a distance and a direction
for the next victim. The signal of victim V1 is masked
temporarily.
• Travel in the new direction indicated to locate the si-
gnal of victim V2.
• Once the device has honed in on victim V2, the device displays CE again AND all directional diodes are switched on
simultaneously: this means that your device has indeed honed in its reception on the new signal
• Once this device has honed in on the new signal, it operates in the standard way for a single victim buried. Operate
in secondary and final search if necessary.
N.B: The BLOCKING function (or masking) operates when the buried devices are dissociated one from another in terms
of emission. One device may conceal another. Ensure that you control the whole of the avalanche.
If, having activated the BLOCKING function, your device leads you back to the first victim V1, repeat the procedure. This
means that the device has not honed in its signal on V2.
If CE is still displayed without giving directions, remove from V1 location and repeat the procedure with the emitting/
receiving button.
