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
light up, meaning 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 emitting the signal which is the
strongest, and therefore theoretically 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
device, quickly activate selector into the emitting position followed by the receiving posi-
tion. 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 pictogram
scenario is present .

• Remain level with the discovered victim V1
ving selector. You are then in BLOCKING MODE
3 seconds 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 signal of victim V2.
• Once the device has honed in on victim V2, the device displays CE again AND all directional
arrows 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.
