Like all transceivers, the Barryvox® contains shock sensitive
ferrite antennas. Therefore, you should handle it with utmost
care!
Store the device and the carrying system in a dry spot that is
protected from extreme cold or heat and direct sunshine.
Always check the result of the self- and battery test, pay atten-
tion to alert messages and carry out the group check.
It is your responsibility to frequently check your Barryvox® for
mechanical damage of the casing, proper function of the main
switch, battery compartment cover as well as cleanliness and
mechanical integrity of the battery contacts.
To ensure the proper performance of the transceiver, it is
highly recommended that you send your device to an offi cial
Barryvox® service center once every three years for a func-
tional test. The recommended date of the next check can be
viewed under «Maintenance» in the shut down sequence of
the device. (see chapter «Periodic Checks» of the Barryvox®
Extended Reference Manual).
Interferences
Always avoid having other electronic devices (e.g. mobile
phones, radios, headlamps, cameras), metal objects (pocket
knives, magnetic buttons), or other transceivers close to (20
cm in SEND; 50 cm in SEARCH) your running avalanche
transceiver.
You should not wear clothing with magnetic buttons! Users of
pacemakers are advised to carry the device in a secure pants
pocket. Consult the manufacturer’s instructions with regard to
the impact on pacemakers.
When searching, hold the device at a minimum of 50cm
away from these objects and turn off any electronic
devices, if possible. It is highly recommended to turn OFF
mobile phones!
HANDLING THE BARRYVOX®
USER MANUAL

Batteries
Only use alkaline (LR03/AAA) batteries of the same type.
Always insert 3 new batteries of the same type. In case these
batteries need to be removed, the same 3 batteries or 3 new
batteries must be reinserted. Never use rechargeable batteries
and always replace all the batteries at the same time.
Make sure the lid is properly closed and that the device and the
batteries stay dry
Use a fi ngernail or the leash clip to slide battery door to the left,
and it will swing open.

Periodically inspect the battery compartment. Clean or dry it, if
needed, since moisture can cause corrosion.
Avoid touching the contacts with your hands, use a clean cloth.
A reliable power supply is crucial for safe operation.
When storing or not using the transceiver for an extended
period of time (summer, travelling,
shipping), remove alkaline batteries and leave the battery
compartment
open. The warranty becomes void if batteries have leaked!

The test is successful if you can clearly hear beep sounds from each participant‘s transceiver
within the range indicated on the display.
The members of the party must be spread out appropriately to avoid mutual interference.
The indicated test distance must not be shortened, or the group check becomes very unreliable.
Once all the participant‘s devices are tested, the group check is concluded. The group leader’s
transceiver must be switched to the SEND mode.
If no tone is heard within the indicated range, the device must not be used.
Further procedure: 1. Check if the device is switched to SEND.
2. Replace the batteries.
3. Have the device checked by the manufacturer.
Chapter «Maintenance and Repair» in the Barryvox® Extended Reference Guide).
If your Barryvox® detects that the transmit frequency of the tested device is out of tolerance, a
warning message will be shown. In this case, repeat the test with 5m distance between the par-
ticipants to identify the defective transmitter. Such devices must be checked by the manufacturer.

The SEND mode is the normal operating mode outdoors or in
all other situations in which there is a risk of avalanches.
Each time the SEND mode is activated, this is
confirmed by an ascending triple beep sound.
Each individual signal pulse is tested. If the
test is successful, this is confirmed by a blink
of the red SEND-Control LED.
If the device detects that the SEND function
is compromised, the red SEND-Control LED
stops flashing and screen shows an alert
message.
To save battery power, the LCD screen is automatically deac-
tivated in the SEND mode, but can be activated any time by
pressing any button.

as found. Excavate the buried subjects
already found while the search continues,
unless the burial depth is particularly deep. (See chapter «Mul-
tiple Burials» in the Barryvox® Extended Reference Guide).
Automatic Revert to SEND
For the safety of the rescuers, the device automatically switch-
es into SEND mode after 4 minutes without user interaction or
motion.

le système de fi xation à un emplacement sec, protégé des
températures extrêmes – basses et élevées – et à l’abri des
rayons directs du soleil. Veuillez toujours observer le résultat de
l’autotest de l’appareil et du test des piles, ainsi que d’éven-
tuels messages d’erreur, et e ectuez le test de groupe.
Nous vous recommandons en outre de vérifi er votre Barryvox®
régulièrement et sous votre responsabilité, notamment les
dégâts mécaniques du boîtier, le fonctionnement correct de
l’interrupteur principal et du couvercle du logement des piles,
ainsi que la propreté et l’absence de corrosion des contacts
des piles.
Il est vivement recommandé de faire vérifi er le fonctionnement
de l’appareil tous les 3 ans. A cet e et, envoyez votre appareil
à un point service o ciel Barryvox®. La date du prochain
contrôle peut être a chée sous «Entretien» lors de l’arrêt de
l’appareil. (Chapitre «Contrôle périodique par un point service
Barryvox» dans le manuel de référence Barryvox®.)
Perturbations
Evitez la présence d’appareils électroniques (par ex. téléphones
mobiles, appareils radio, lampes frontales, app. photo), d’objets
