ARVA 3 Axes Mode D'emploi page 9

Exclusive features of the ARVA 3 AXES:
• A powerful 457 kHz ±20 Hz transmitter with transmission level independent of battery power.
• In numerical (standard) mode, the search band width is 40 m.
• Multiple victim indicator and automatic synchronisation on closest victim.
• In Advanced (= analogue) mode, indication of a scale of progress and, in multiple victim situations, indication
of estimated distances along field lines.
• Function: blocking of the victim which allows the isolation of the victim found to its vicinity in order to locate further
victims (in the case of multiple burials).
• Auto-control of frequency adjustment and transmission level every 5 minutes.
• 16 bit processor with extremely fast analysis speed.
installing batteries
The ARVA 3 AXES operates exclusively with four standard LR03 alkaline batte-
ries. Open the battery compartment cover
four batteries should be of the same brand and be replaced at the same time.
Insert the batteries carefully in the order shown inside the compartment.
N.B.: Do not store the unit at a temperature of less than 0°C to avoid damaging
the batteries. DO NOT USE rechargeable batteries. Remove the batteries if the
unit is not used for any length of time.
switching the unit on
■ Fasten the On/Off strap
1
■ Auto-control: the direction diodes
the LCD screen comes on. 3 beeps are emitted if the loudspeaker is in
working order.
■ Check your batteries using the battery life indicator scale levels
9 11 levels: 99,90, 80, 70, 60, 50, 40, 30, 20, 10, 0.
■ The LCD screen then goes off and the central diode
indicate that the unit is in transmit mode.
■ Check Transmit/Receive functions before setting out. The
person checking the unit puts his ARVA in transmit mode and all the other
members of the group check that their ARVAs detect the signal properly in
receive mode . The operation is to be repeated in the opposite direction
so that ALL the ARVA units in the group are checked in both transmit and
receive modes.
Possible anomalies...
The ARVA 3 AXES performs a self-test every 5 minutes to check the state of the
batteries, frequency setting, transmission power, etc.
If the unit detects an anomaly, a 5-second beep is emitted,
3 times, separated by 5 minute intervals. This means one of two things:
• The battery charge has dropped to 20% (the unit can still transmit for 48
hours or search for half an hour). After the 5-second beeps, 20% will stay
displayed on the LCD screen to remind you to change the batteries as soon
as possible.
• Technical problems connected with transmission or programming: after the 5-
second beeps, the LCD screen displays Er (= Error). Do not set out with
any unit displaying this message.

information for your own security
Whenever you leave marked-out ski runs or trails, you are in an area
where there are certain risks, particularly of avalanches. When moving
around in the mountains, you do so at your own risk:
• Before setting out, check the local weather with a reliable
weather station or professional mountain guides and carry the right
equipment. In particular, take an ARVA and carry a shovel and a
probe. But remember, this equipment will not detect avalanches or pro-
vide complete protection and to be fully effective, you need to familiarise
yourself with the use of the ARVA beforehand!
• Never go off on your own and do not follow any trail
you happen to see: they are no guarantee of safety. If there is any
doubt about the stability of a slope you have to cross, YOU MUST leave
a good distance between one another or better, cross it one by one.
Keep a good eye on one another.
• Finally, it is best to give up if you are not sure! Be careful: snow
conditions change, and with them the risk of avalanches. Get to know
about avalanches. In France, a free catalogue and documentation can be
obtained from ANENA (Association Nationale pour l'Etude de la Neige et
des Avalanches, - tel. 04 76 51 39 39 / www.anena.org).
using the arva
The ARVA 3 AXES has two operating modes:
■ Standard (numerical), involving use of the right and left directional
arrows. The device automatically locks on to the closest victim. Follow the indi-
cations given in the form of figures and the direction shown by the red diode. If
pictogram 6 lights up, the device has detected multiple victims.
■ Advanced (analogue with numerical aids), in which receiver sen-
sitivity is adjusted with the + and - buttons. In analogue mode, the Advanced
symbol is displayed on the screen with a sensitivity level value (1,2,3,4,5,6,7,8
or 9). 9 corresponds to greatest sensitivity (distant search) and 1 to lowest sen-
sitivity (close search). In this mode, the device shows all the signals received. If
there are multiple victims, it indicates the estimated distances to each one.
■ BLOCKING function (masking) of the signal:
This function allows the temporary masking of the signal of the first victim dis-
covered. As soon as you activate the BLOCKING function, the signal of the closest
field is masked and the device displays the second closest signal detected. This
function is very useful for scenarios of multiple burial of victims.
