time. The technical and product specications may
change without prior notice for future versions of this
and other devices.
1.2/ PRACTICE - RESPONSIBILITY
Practice makes perfect, and knowing how to properly use
your device is essential in an avalanche search. Off-piste
skiing, ski touring, and ski mountaineering are activities
with inherent risks, and wearing a transceiver should not
inuence your decision making in risky locations. Know
when to turn around.
1.3/ STORAGE - BATTERY
Store your transceiver in a cool and dry place, away from
direct sunlight. Remove the battery when storing the de-
vice for long periods of time (in summer). Your transceiver
is no longer under warranty if the battery leaks. Check
your device on a regular to make sure that the OFF/SEND/
SEARCH selector switch and screen function properly,
and that there are no traces of corrosion in the battery
compartment.
The EVO5 operates exclusively with one AA/LR06 alkaline
battery. Do not use a lithium or rechargeable battery. The
label in the battery compartment is important for custom-
er service, do not remove it. After changing the battery,
make sure that the cover is closed properly.
Important for Switzerland: appendix 4.10 for standard
SR814.013 applies to batteries.
CAUTION: There is a risk of explosion if the
battery is thrown into a re or replaced by the
wrong type of battery. Follow the instructions
on how to properly dispose of used batteries.
2/ TRANSMIT MODE
2.1/ TURNING ON THE DEVICE
The device is off when the OFF/
SEND/SEARCH selector switch
is in the top position and the
selector’s white arrow points
to “OFF”.
EN
5
To turn on the device, push the
OFF/SEND/SEARCH selector
(located on the upper right-
hand side of the device) down
until the lock button mechan-
ically locks it into place (the
white arrow should point to
“SEND”).
When the device turns on, it automatically checks that all
main functions are working properly. Verify that the au-
to-test runs correctly and pay close attention to any error
messages that display when turning on your device.
The device then displays the software version installed
and remaining battery life. We recommend that you re-
place the battery as soon as it drops below 50%. Holding
down the marking button in transmit mode will allow you
to check battery life left at any time.
The selector is properly locked when, in transmit mode,
the lock button pops out and you hear it click into place
and you cannot push it down any further.

Once the start-up phase is complete,
the device automatically switches
to transmit mode. A blinking arrow
in the upper middle of the screen
conrms that your transceiver is in
transmit mode.
2.2/ WEARING THE DEVICE
POCKET OPTION
Once the EVO5 is in transmit mode, make sure that it is
connected to the elastic attachment lanyard (the device
is delivered attached to the lanyard), and then verify that
the carabiner on the elastic
attachment lanyard is con-
nected to the waist belt.
Position the EVO5 in a zippered pant pocket for the entire
duration of your outing. The zipper slider should be fully
closed, leaving only enough room for the elastic cord to
exit. Adjust the belt around your waist and then buckle it.

Make sure that you do not place any other contents in
the pocket carrying your EVO5 avalanche transceiver. Do
not place a cell phone in the same pocket and follow the
distance guidelines detailed in paragraph 5, “INTERFER-
ENCE”.
2.3/ WEARING THE DEVICE
HOLSTER OPTION
If you have an EVO5 HOLSTER (sold separately as an ac-
cessory), make sure that the carabiner on the elastic at-
tachment lanyard is connected to the holster’s waist belt
(2 positions, left or right), position the device in the holster
with the screen facing out, and then buckle the holster
closed. The EVO5 should always be worn over a base layer
and as close to your body as possible.

2.4/ TURNING OFF THE DEVICE
To turn off the device when it is in transmit mode, press
the lock button to unlock the OFF/SEND/SEARCH selector
switch and then push the selector into the upper position,
with the white arrow pointing to “OFF”. You will then be
asked to conrm that you want to turn off the device by
pressing on the marking button.
3/ SEARCH MODE
In the event of an avalanche, to switch from search to
transmit mode, take the device out of your pocket or hol-
ster and press the lock button down to unlock and push
the selector switch down to the “SEARCH” position.

3.1/ GROUP AND FREQUENCY CHECK
Before starting your outing, check to make sure that
everyone’s device is in transmit mode and working prop-
erly. The group leader should switch their device into
GROUP CHECK mode to check the devices of the other
members in the group.
When turning on the EVO5 in transmit mode, it will
prompt you to switch to GROUP CHECK mode. To enter
GROUP CHECK mode, push on the marking button when
the GROUP CHECK icon is blinking in the upper part of
the screen.
PRESS
1M
You will then be able to test your partners’ devices one by
one by positioning your device 1m away from each device
you check.
In GROUP CHECK mode, the EVO5 starts by analyzing the
transmit frequency. If the frequency does not comply with
current standards, a “no” message will appear indicat-
ing that the device being checked is defective and should
be sent to customer service. If the frequency meets the
standard, a distance reading will display on your screen
and you may then proceed to checking transmit power :
10
• If the distance displayed alternates
between 0.5m and 1.5m, and you are
positioned 1m from the device being
checked, your device will emit a standard
search beep indicating that the transmit
power meets standard requirements.
• If the distance displayed seems
strange, this means that the transmit
power might be faulty and that the de-
vice should be sent to customer service
for further inspection and maintenance.
Make sure that the group leader’s device is also checked
once the group check is nished. Push on the marking
button to switch to transmit mode.
3.2/ RESCUE
3.2.1/ STEP 1: SIGNAL SEARCH
To search for a signal, move through the avalanche de-
bris using one of the two techniques illustrated in the di-
agrams below.
It is important to point your transceiver in the direction of
the avalanche, parallel to the slope. Listen carefully for
the rst signs of a signal while also paying attention to
any visual clues (poles, skis, and clothing). As soon as you
receive a signal, a victim icon appears on the screen.

3.2.2/ STEP 2: COARSE SEARCH
As soon as you receive a signal, place the device in the
palm of your hand, parallel to the slope, and pointing in
the direction indicated on the screen. Pay close attention
to the distance and the direction indicated on screen. For
the initial signal received (the strongest signal), the rst
avalanche victim icon appears on screen, and once locked
in, the icon will start to blink. The victims are ranked by
signal strength, from strongest to weakest. So the victim
The victim icons are located on the bottom left of your
screen. The “+” icon indicates that there are more than
three burials.
corresponding to the strongest signal will blink on your
screen. If you come close to another burial during your
search, the icon corresponding to this victim will also
start to blink.
If you are not heading in the right direc-
tion, an alarm will sound and “u-turn”
icon will appear on screen indicating that
you should turnaround to head in the
correct direction towards the victim(s)
burial zone.
In a complex situation where there are multiple burials
or in an environment where there is a lot of interference,
the device might reach analysis overload. In this case, dis-
tance yourself from that specic area and then return by
following another direction.
