NOTE: This equipment has been tested and found
to comply with the limits for a Class B digital de-
vice, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protec-
tion against harmful interference in a residential
installation. This equipment generates uses and
can radiate radio frequency energy and, if not
installed and used in accordance with the instruc-
tion, may cause harmful interference to radio
communications. However, there is no guarantee
that interference will not occur in a particular in-
stallation. If this equipment does cause harmful
interference to radio or television reception which
can be determined by turning the equipment off
and on, the user is encouraged to try to correct
Disposal of electronic instruments by users from private house-
holds in the European Union. This symbol stamped on the product 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 ofce 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 res-
idence, contact your local city hall, waste management company, or the
store where you purchased the product.
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.
Search for the victim
by probing in concentric
spirals progressively
away from the minimum
distance point detected
by your ARVA. Probe
perpendicular to the
slope.
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.
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 recom-
mend that you keep your transceiver as far as possible from
sources of electrical and electromagnetic activity.
Statistically, shoveling takes at least as much time as
the ARVA search. It is important to take a methodic approach
to shoveling.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
