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

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. In order to switch the device, quickly activate selector

into the emitting position followed by the receiving 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 pictogram

• 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 signal 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

• When you reach victim V2, 3 little points appear under the multiple victims icon

at least a third signal around you. Mark the signals one by one.

• 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.
