PRACTICE:
Practicing and being well-trained in using your transceiver
is essential in order to conduct a successful search in the
event of an avalanche.
RESPONSABILITY:
Skiing off trail or skiing in the backcountry are activities
that present inherent risks. Wearing a transceiver should in
no way influence your decision making when in avalanche
terrain. Know when to turn around.
STORAGE:
Store your device in a cool and dry place. Remove the
batteries when storing for long periods of time. The device
is no longer under warranty if the batteries leak.
WARRANTY:
Your device has a 5-year warranty. We recommend sending
your transceiver in for maintenance on a regular basis:
once every 3 years for amateurs, and once every two years
for professionals.
REGISTRATION AND UPDATES:
Every ARVA transceiver has a unique identification number.
Registering your device on www.arva-equipment.com allows
us to link your contact information your device to for optimal
tracking (maintenance, customer service, software updates,
etc.).
BATTERIES:
The ARVA transceiver only operates with 4 standard Alka-
line AAA/LRO3 batteries. Do not use rechargeable or lithium
batteries. The batteries should all be replaced at the same
time. The label in the battery compartment is important for
all servicing procedures, do not remove it.
IMPORTANT FOR SWITZERLAND: APPENDIX 4.10 FOR STAND-
ARD SR 814.013 APPLIES TO BATTERIES.
CAUTION: THERE IS A RISK OF EXPLOSION IF THE BATTERY
IS THROWN INTO A FIRE OR REPLACED BY THE WRONG TYPE
OF BATTERY. FOLLOW INSTRUCTIONS ON HOW TO PROPERLY
DISPOSE OF USED BATTERIES.

INITIAL START-UP
1-“CLIP FOR SAFE”
Once you are wearing your transceiver, it automatically
turns on as soon as you connect the strap. This is a simple
and easy way to be 100% certain that your ARVA is working
as soon as you start your outing. For more advance users
(professionals) who do not want to use the clip for safe
feature, a special holster is available for purchase as an
accessory.
2-WEARING THE DEVICE
Your ARVA must always be worn on top of your base layer.
Your ARVA should always be covered by at least one layer
of clothing to protect it from the cold and impacts.
3-BATTERY CHECK
Just after turning on your device, it will indicate the battery
level. We recommend that you replace the batteries as soon
as they drop below 50%.

GROUP CHECK SIGNAL SEARCH
SEARCH MODE
To switch to search mode, push the
S/T button up with your thumb.
• The Group Check function allows the
group leader to verify that all other
transceivers are working properly.
• To enter Group Check mode, press
the marking button within 5 seconds
after turning on the device (in transmit
mode).
• The device will verify all transmitting
signals within a 0.5 to 1.5 meter radius,
and emit a beep to confirm that they
function properly.
• To exit Group Check mode, press the
marking button.
Start searching for a signal based on one
of the two diagrams below.
Slowly rotate back and
forth to try to detect the
signal(s).
To maximize the range of your ARVA :
It is important to point your ARVA in the
direction of the avalanche, parallel to the
slope and not pointing upwards towards
the sky.

During the coarse search :
• Carefully follow the distance and
direction indicators on the screen
• Point the device in the direction of the signal
Once within 3 meters of the victim, your ARVA no longer
indicates a direction and you must start bracketing (search-
ing in a cross pattern).
• In a complex situation with multiple victims, the device
may have trouble analyzing the signal. In this case, move a
few steps away and then return towards the critical point
by following another direction.
It is then much quicker to start probing once you have de-
fined the probable burial zone within a less than one-meter
range.
• Search in a calm and
focused manner.
• Slow down as you ap-
proach the fine search.
• If the displayed distance
starts to increase even
though you are moving in
the direction indicated by
the arrow, turn around.
1. Lower your device to near
snow level.
2. Move your device in a cross
pattern to locate the point
where the distance reading is
the lowest.
DURING THE SEARCH, PAY ATTENTION TO VISUAL CLUES
SUCH AS POLES, SKIS, CLOTHING, ETC.

MARKING FUNCTION
To mark the victim, press on the
“marking” button. The device will
switch to victim B.
A
B
When you are less than
3m from the first victim
you have the option of
marking the location
in order to continue
searching for another
signal. In the illustration
example, you can mark
victim A.
Example of
fine search
technique
•
1er point
de sondage
Victims appears on the left part of your
screen. When a victim is marked a flag
appears close to it. The + indicate that
there is 3 or more victims.

The V-shaped conveyor
technique allows you to
optimize the excavation
phase of shoveling.
As soon as the person
is uncovered, it is
important to turn their
transceiver off imme-
diately.
Search for the victim
by probing in concen-
tric spirals progressive-
ly away from the min-
imum distance point
detected by your ARVA.
Probe perpendicular to
the slope.
Statistically, shoveling takes at least as much time as the
ARVA search. It is important to take a methodic approach to
shoveling.
Certain electronic devices as well as electrical and elec-
tromagnetic installations can significantly interfere with
transceiver signals.
These sources are:
• carried: smart phone - analog radio - camera - heart rate
monitors - GPS - etc.
• permanent: relay towers - power lines / electrical generat-
ing equipment - ski lifts, etc.
In order to reduce the risk of signal deterioration, we rec-
ommend that you keep your transceiver as far as possible
from sources of electrical and electromagnetic activity.

IN SEARCH MODE:
Move all metallic and electronic devices at least 50cm
away from your transceiver.
During an active search, we recommended turning off all
devices except:
• Analog radio
• Headlamp without dimmer
• Watch without a radio function
• Backup devices in the event of a secondary avalanche
Means of communication:
We recommend turning off all digital telephones and radios
during the active search phase. All calls should be made at
least 25m away from the individuals conducting the active
search.
IN TRANSMIT MODE:
Move all metallic and electronic devices at least 20cm away
from your transceiver.
Disposal of electronic instruments by users from private house-
holds in the European Union. This symbol stamped on the prod-
uct or its packaging indicates that the product is not allowed to
be disposed of with household waste. It is your responsibility to
bring your electronics waste to a designated recycling office for
proper disposal. Separate disposal and recycling of your waste
will contribute to preserving our natural resources and ensure
an environmentally-friendly disposal safer for public health. For
more information regarding the closest recycling center to your
