5/ INTERFERENCE
Certain electronic devices as well as electrical and elec-
tromagnetic installations can significantly interfere with
transceiver signals.
These sources are:
• Carried: smart phones, radios, cameras, heart rate
monitors, GPS, etc.
• Permanent: relay towers, power lines / electricity gen-
erating equipment, ski lifts.
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.
5.1/ RECOMMENDATIONS IN SEARCH MODE
Move all metallic and electronic devices at least 50cm
away from your transceiver.
When conducting a search, we recommend turning off all
electronic devices except analog radios, headlamps with-
out an automatic regulator, watches that do not have a
radio feature, and backup transceivers in the event of a
14
secondary avalanche. Turn off all telephones and digital
radios during an active search. All telephone calls should
be made at least 25m from the people conducting the ac-
tive search.
5.2/ RECOMMENDATIONS IN TRANSMIT
MODE
Move all metallic and electronic devices at least 20cm
away from your transceiver.
5.3/ ACTIVE INTERFERENCE MANAGEMENT
With the huge increase in the use of wearable electronic
devices, the potential has increased for electromagnetic
interference of the search signal. These incidences have
primarily been observed near ski areas. Active interfer-
ence management is a default setting on the EVO5, al-
lowing your device to detect interference zones and, if
necessary, reduce the search strip width. The user can
then adapt their search strategy accordingly.
