SHOVELING
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 electromag-
netic installations can signicantly interfere with transceiver
signals.
These sources are :
• carried: smart phone - analog radio - camera - heart rate
monitors - GPS - etc.
• permanent: relay towers - power lines / electrical generating
equipment - ski lifts, etc.
In order to reduce the risk of signal deterioration, we recommend 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
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 immediately.
• 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.

INSERTING BATTERIES AND RECOMMENDATIONS.
The ARVA EVO4 only operates with 4 standard Alkaline
AAA/ LRO3 batteries. Open the compartment on the back
of the device to insert the 4 batteries. The 4 batteries should
always be from the same brand and replaced at the same time.
NEVER USE RECHARGEABLE OR LITHIUM BATTERIES.
These batteries lose their charge all of a sudden and do not
discharge gradually. Remove the batteries when the device is
not in use for long periods of time (especially in summer). If the
batteries leak inside the device, the warranty no longer applies.
IMPORTANT FOR SWITZERLAND: APPENDIX 4.10 FOR
STANDARD 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.
LABEL FOR PRODUCT SERVICE
A sticker indicating the unique reference number for your
device and the warranty date is located inside the battery
compartment. Please leave this sticker in place in order to
properly service the device.
PRACTICE AS MUCH AS POSSIBLE: MORE IMPORTANT
THAN THE PERFORMANCE CAPABILITIES OF YOUR ARVA,
KNOWING YOUR DEVICE WILL MAKE ALL THE DIFFERENCE.
TAKE THE TIME AT THE BEGINNING OR END OF THE SEASON
TO SEND YOUR ARVA IN FOR MAINTENANCE.
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.
“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.
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%.
• 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 conrm that they function
properly
• To exit Group Check mode, press
the marking button
SWITCHING TO SEARCH MODE
SEARCH MODE
To switch to search mode, push the
S/T button up with your thumb.
Start searching for a signal based on one of the two
diagrams below.
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.
Slowly rotate back and forth
to try to detect the signal(s).
During the coarse search.
• Carefully follow the distance and direction indicators
on the screen
• Point the device in the direction of the signal
• Search in a calm and
focused manner
• Slow down as you
approach the ne search
• If the displayed distance
starts to increase even
though you are moving in
the direction indicated by
the arrow, turn around
• 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.
DURING THE SEARCH, PAY ATTENTION TO VISUAL CLUES
SUCH AS POLES, SKIS, CLOTHING, ETC.
Once within 3 meters of the victim, your ARVA no longer
indicates a direction and you must start bracketing
(searching in a cross pattern).
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
It is then much quicker to start probing once you have
dened the probable burial zone within a less than
one-meter range
