Congr atulations on the purchase of you r new
PULSE Bar ryvox®.
This user manual explains the functionality and use of
the PULSE Barryvox®. The PULSE Barryvox®is a revolutionary avalanche transceiver, which you will understand quickly and which is very easy to use.
A transceiver does not protect you against
avalanches!
As a winter outdo or enthusiast, you must conside r all
possi ble avalan che prevention measur es and plan
your trip s c arefully. Com panion rescue – the worst
case – must be practiced frequently. Under the stress
of an acciden t, this is the only way you will be able to
locate and dig out a companion quickly and efficiently. Despite practice and all the technolo gical
advan cements, by far not all of the complete ly buried
avalanche victi ms are rescued! An avalanche buri al is
always life threate ning.
Impor tant information on these topics can be found in
the chapters on compani on rescue and avala nche
theor y.

If you carry the B arryvo x
in a pant pocket, the zipper must rema in closed
for the duration of the trip.
Always use a secured
pocke t ( see illustration). If
possi ble, attach the wrist
loop to your pant s o r
secur e i t around your belt.
2.5 Turning the Device On
When the main switch is moved from the O FF to t he
SEND or SEARCH positions, the transceiver is turned on.
While starting, the device condu cts a s elf-test.
The micro processor, the antennas, the sensors, and
the displ ay are checked. If the battery level is lo w,
the self- test will not run.
If the self-t est is completed successf ully, t he display
will show «OK» and the transce iver will beep three
times .
The remaining battery level is displayed as a percentage.
If the self-t est fails, an error message is displayed for
20 second s a long with an acoustic warning .
The meani ngs of the different error messag es are
descr ibed in the chapte r « Troubleshooting» .
Test your Barryvox at home prior to your trip. Turn the
trans ceiver on an d m onitor the s elf-test and the battery level. T his gives you the opportunity to re place
low batteries and have an ev entual defect repair ed
befor ehand.

Setup
2.2 Handling the Barr yvox
As all transc eivers, the Barryvox contains shock-se nsitiv e f errite antennas. Therefore, you should handle it
with utmo st care!
Store the device and the carry ing system in a dry
spot that is protected from extreme cold or h eat and
direc t s unshine.
It is recomme nded that you have the functionality
teste d a t regular intervals (see chapter « Periodic
Check s»).
2.3 Interferen ces
As a matter of princi ple, avoid havi ng other electronic
devic es (e.g. mobile phon es, radios, headlamps),
metal objects (pocket knives, magn etic buttons), or
other transceivers close to your runni ng avalanc he
trans ceiver. T he PULSE Barryvox®conta ins a m agnetic compas s. You should not wear clothing wit h
magne tic but tons! Users of pacemakers are
advis ed to ca rry the device on their right side
(adju st the l ength o f the ca rrying straps ). Consult
the manufacturer’s instructions with regard to the
impact on pacemakers.
When sear ching, hold the devi ce at a minimum of
50c m a way from these objects and turn off a ny electroni c d evices, if possible. It is highly recommend ed
to turn off mobil e p hones!
The Applic ation Safety Guide of the Barryv ox contains
an exhaus tive list of allowed equipment as well as a
detai led list of possible limitations.

2.4 Carrying Po sitions
Regar dless of the carry ing position, the d isplay
shoul d a lways face your body!
The de tectio n of vit al data is o nly pos sible if you
carry the de vice in the carrying s ystem.
(Chap ter «Triage Criteria an Vital Data»)
Befor e y ou use the device for the first time in the outdoors , o r when you decide to carry the transcei ver in
a differe nt manner, we recommen d t hat you test the
vital data sensor (Cha pter «Vita l S ensor Test»).
2.4.1 Carryin g Syste m
(Reco mmended Carryin g Position )
The carrying system has to be put on your innermost
layer of clothing prio r t o beginning t he trip (see illustration) and has to be worn on your body for the duration of the trip. The transcei ver sha ll always
remai n cover ed by one layer of cloth ing. The
devic e i tself is inserted into the carrying system
accor ding to the illustration. It shou ld always rema in
ancho red to the base plate of the carrying system
using the red h ook on the wrist loop.

After 5 minutes in the group check, the transcei ver
autom atical ly switche s t o t he SEND mode. The user is
warne d a head of time by an acoustic alarm. This
autom atic switching can be prevented by pressing
any button within 20 seconds. Aft er the group check,
the trans ceiver must be s witched t o t he SEND mode
by pressi ng any button.
Two-Way Group Check
We recomme nd you perform a two -way group check
in which the SEND and t he SEARCH functionali ty are
check ed individually!
The membe rs of t he party activate the group check
on their tran sceivers or set them to a lo w r eceive volume. The leader s witches his or h er transceiver to
the SEND mode and e nsures that all party members
can recei ve. Subseque ntly, t he party members switch
their transceivers to SEND, and the leader activates
the group check or sets the transceiver to a low
recei ve volume. The SEND mode of all transc eivers is
check ed, and ultimately the leader swit ches his or
her trans ceiver to SEND.

2.6 Battery Le vel Ind icator
The follo wing table gives you average values for the
battery levels.
The remai ning batte ry level can only be displ ayed

The trans ceiver sounds a warning if the battery level
is below 20% a t s tartup .
2.7 Group Check
Befor e a party takes off, the trans ceivers o f a ll the
party members must be ch ecked. To con duct this
test, the function group chec k i s a ctivat ed on a sin gle
trans ceiver within the party. Activate the group check
by switching the device from OFF to S END and pressing eithe r o f the keys within the first 5 seconds. After
a few seconds , the device will automatically activ ate
the group check. Make sure all the other transceivers
of the party are in SEND mode.
The test is succe ssful if all the member s of the party
can clearl y hear beeps within the range indica ted on
the displ ay. The members of the party must be spread
out appropriately to avoid mutual interference. If the
indiv iduals are t oo close to each other, the group
check ’s re sults become increasi ngly unreliable.
If no tone is hear d withi n the in dicated range, the
devic e may no t be use d, and the device or its batterie s must b e inspe cted further, as nee ded.

4.1 Search Phases
In an avalanche search, the follo wing phase s are d istingu ished:
●
Prima ry search phase
●
Secon dary searc h phase
Primary
search phase
Secondary
search phase
Coarse search
Pinpointing
13
4.1.2 Secondary Sear ch Phase
The basic pattern of the prima ry search is suspended
and the signa l i s followed to the buried subject.
• Coars e Searc h: From where t he signal is first
detec ted to the approximate locat ion of the
burie d s ubject.
• Pinpo inting Phase: Pinpointin g o ccurs in the
immed iate proxi mity of the buried subject using
the trans ceiver together with a probe pole.
4.2 Auto-Rever t to SEN D
Auto- revert to SE ND automatically switches the
trans ceiver from the SEARCH mode to the SEND
mode if no user interaction or movement occurs during a certain amount of time (default 8 minutes) .
Prior to revertin g, the device will soun d a n audible
alarm . Reverting can be a voided if either of the keys
is presse d w ithin 20 seconds of the alarm.
This sett ing automa tically reverts a transceive r, which
was unint entionally left in SEARCH mode (after a
searc h o r an exercise ), back to the SEND mode.
In case rescu ers are buried in a second avalanche,
this func tion allow s t hem to be l ocated using transceive rs.
4.3 Analog Search Tone
Just as in traditional analog transceivers, the analog
tone is just received by one antenna. The change in the
distance indication can therefore deviate from the
change in tone volume. Depending on the relative orientation of the transmitter to the receiver, the tone volume
and the distance indication may both decrease while
approaching the buried subject.
4.4 Standard Mode
As soon as the device is switched to SEARCH, it is
operating in standard mode. This mode enormously
facilitates a rapid location of a buried subject.
12
SEARCH Mode
4.1.1 Primary Sea rch Pha se
From the start of the search until you cl early hear the
first tone, you are in the primary search phase.
Durin g t he primary search, the avala nche surface is
searc hed systematically until you pick up a signal.
The objec tive of the primar y search phase is to detect
a signal.
The PU LSE Bar ryvox®uses t he symb ol as a
gener ic inst ruction to apply one of the following
searc h patte rns for new signals!
To optimi ze the r ange, rotate the transc eiver
aroun d all ax es.
Once a signal is re ceived, maintain the devi ce orientation and continue walking until the signal can be
heard clearly. Th e p rimary search phase is concluded.
Regar dless of the opera ting mode, the follo wing

Coars e S earch
The analo g t one is the first signal that is received a t
long dist ance.
If the distan ce to t he buried subject is less than
approx. 6 0 m eters, the dista nce and direction are displaye d. The sensitiv ity (volume) of t he receiver is
adjus ted automa tically to o ptimize the processi ng of
the signa l. The distance can n ever be determined
exact ly. The numbers must be interpr eted as relati ve
dista nces. Whether the numbers are increasi ng or
decre asing is more important than the abso lute numbers. The closer you are to t he transmitting devic e,
the more prec ise the indicated distance is.
Hold t he tran sceiver horizontally in fron t of you
and pr oceed i n the di rection indicated by the
arrow. If the dis tance i ncreases, you ar e moving
away from the victim. Continue the search in the
oppos ite dir ection. The transceiver will lead you to
the burie d s ubject quickly and relia bly.
Do not move backwards, otherwise the direction
indic ation w ill be i ncorrect.
The -key is used to manually select a specific buried subject.
If none of the buried subjects
are selected, the device
displays the symbol for the primary search phase and
advises you to search the avalanche for additional signals.
If you are in close proximity of a
buried subject, you can mark
that location by pressing the

4.4.3 Search for Multiple Bur ied Sub jects
Using the Sta ndard Mode
In standa rd mode, the transce iver attempts to analyze
all the detec table signals and to determin e t he number of buried subjects. This is po ssible, bec ause all
the signa ls from one transmitter displ ay characteristics, which are distinguishab le from the signals from
other transmitters. The more unique the sign al character istics are, the more accurat ely the signals c an
be distin guished and located (pattern recognition). By
autom atical ly associa ting the signals with their
respe ctive sources, multiple burial situa tions can be
solve d w ithout applying specific search tactic s.

The rescu er now searche s f or additional buried subjects while the display shows the symbol f or the primary search phase to indicate that the rest of the
avalanche surfa ce must be searched (Chapter
«Prim ary Search Phase»).
Procedure for multiple burials

If the + sign appears for an extended period of time,
this indi cates that not all the buried subje cts can be
located using the stand ard mode. In this case, it is
advis ed to s witch to the analog mode.
4.5 Analog Mode
In the analog mode, the transcei ver shows distance
and direc tion to the subject with the stronge st signal
and provi des an analog tone. The ana log mod e is
mostl y used w hen a clear dist inction of mul tiple
buria ls is no lon ger pos sible in standard mode.
Switc hing from standard mode to analog mode is
achie ved by pressing and holding both keys at the
same time for t hree seconds.
In analog mode, the directio n i ndicat ion always points
forwa rd, never backwa rds. Monitor the d istance i ndication to ensure you are approaching the buried subject!
4.5.1 Multiple Buried Sub jects i n Analo g Mode
If multip le burials are detected in analog mode, an
icon symb olizing multiple burials is shown on the display . Additionally, you can a lso hear the analog
tones . Thes e are h elpful in di stinguishing the signals
acous tically. The device favors the closest subject.
The detec tion of multiple burials may vary based on
the subje ct’s orientation and distan ce relativ e t o the
rescu er.
Turn off the transceivers of the excavated subjects to
facil itate the furt her search. If you don’ t k now the

highe r c hances of su rvival, in dicate d b y the symbo l, should be located and excavat ed first.
You can find more information on triag e c riteria a nd
vital data in the chapter «Triage Criteria and Vital
Data». The actual priori tizati on of c ertain buried subjects over others is up to the rescuer.
4.4.4 Limitations
The large r t he number of buried subjects is, th e more
diffi cult and time-consumi ng the exact analysis of the
situa tion gets, because of overlapp ing signals. The
more sign als there are, the longer t he signal overlaps
can last. The capabi lity to automa tically detect and
isola te signals from multiple buried subje cts is therefore limi ted.
Numbe r o f Burials
The calcu lated numb er of b urials is di splayed below
the list of burie d s ubjects. If the transcei ver detects
more sign als than buried subjects in the list, a + sign
is added behi nd the number.
Searc h S uspens ion
Durin g t he search for multiple subjec ts, signals may
overl ap making it impos sible to analyze the signal of
a single buri ed subject. If the signal overl ap lasts
sever al seconds, the rescuer has to interrupt the
proce ss temporarily to avoid deviating from the optimal searc h p ath. The PULSE Barr yvox®will indi cate
the neces sity to suspend the search by displa ying the
word «Sto p». Stand still, and do not move until the
word «Sto p» disappe ars, at which time you can continue to search.
Analo g Tone
Outside of the pinpointing range, the Barryvox alway s
provides the analog tone allowing th e rescuer to verify
the number of signals detected by the device. Counting the number of different to nes provides the number
of buried subjects.
Analo g M ode
If the rescue r d etects problems with the analysis of a
multi ple burial situation, he or she can always switch
to the analog mode (see chapte r « Analog Mode»).

4.5.2 Search Tactics with Multip le, Widely
Scatt ered Bu rials
1.
Mark the loca tion on the avalan che where the «multiple buria l» icon appeared on the display or wh ere
you left the prim ary search pattern.
2.
Searc h f or the first buried subject using the informa tion on the displ ay along with the analo g tones. Once
this subj ect is located , you or o ther rescuers should
dig him or her out immediately.
3.
Conti nue to search for other buried subje cts by
retur ning to the previously marked point.
4.
Stric tly adhere to the p rimary search pattern and
conti nue down the avala nche path until you are led to
the next subj ect. Initial ly, the transcei ver will want to
take you to the previously located subject , be cause
he or she is still the closest . Ignore these indi cators
until you notice that the tran sceiver is p ursuing a new
subje ct.
Search tactics with multiple, widely scattered burials in analogmode

SEARCH Mode
4.
Maint ain the orientation of the transceiver during this
phase and concentrate on the increase or d ecrease of
the dista nce indica tion as well as the volume of the
analo g t ones.
5.
At the point with the l owest distance reading, you
leave the micro search strip patter n t o pinpoint the
burie d s ubject through bracketing. Once the subject
is located, y ou return to the location where you left
off in order to continue the pattern.
6.
The more buri ed subjects there are and the closer
these are, the tighter the micro search strip grid on
the poten tial search area should be. As a rule of
thumb , the s earch strip width should be between 2
and 5 meters.
7.
Conti nue the patter n, until the distan ce reading in an
entir e s trip never drops below 15. Then revert to the
prima ry search pattern and searc h the rest of t he
avalanche.
The avalanche probe is ve ry helpful in locatin g m ultiple burie d s ubjects i n cl ose proximity.
There are at le ast three buried
subje cts within 15 me ters.
Search tactics with multiple burials in close proximity in analog mode
4.5.3 Search Tactics with Multip le Buri als
in Clo se Prox imity
The inter pretat ion of the acoustic signals is extremely
impor tant in this situa tion. These must be interp reted
in connec tion with the distance readin gs.
Examp le:
You hear three beeps and t he distance reading jumps
betwe en 3.5 and 4.8 m. Therefor e, three buried subjects can be ex pected within a radius of 5 m.
Searc h U sing Micro Search Strips
If you have multi ple bur ials wi thin less than 10 t o
15 met ers, you search using micro se arch st rips.
1.
Locate and dig out the first buried subject.
2.
Back up until the display shows 15 and search the
area in front of you in parallel search strips.
3.
As soon as the distan ce indication reads 15, you have
reach ed the side of the search strip . Advance 2 to 5
meter s a nd return on the next parallel search strip
until this search strip ends as well (distan ce indication > 15).

7.4 Triage Criteria an d Vital D ata
7.4.1 Triage
With limited resources (few re scuers) it is not possible
to locate and dig out all the buried subjects at the
same time. The question arises in which o rder the
buried subjects shall be rescued. Subjec ts with hi gh-
er chan ces of sur vival sho uld be located and dug
out fir st. Besid es simple terrain factors, e.g. drop
over a cliff, the bu rial depth and vital data are an
important triage criteri a.
7.4.2 Vital Data Detection
The PULSE Barryvox®conta ins highly sensitive sensors (g-s ensor) that can detect slight motion of the
body, such as a p umping heart or breathing lungs.
Any motion within a certain maximum lag time is
inter preted as vi tal data. The buried subject belongs
to the category with high chances of survival. It
can be assume d t hat buried subjects, which have
survived the first 35 min, are still able to breat he (air
pocke t), and therefor e h ave increa sed chances of
survival. At the same time, the detectability of vital
data decreases due to hypother mia. T herefore, b uried
subje cts who have trans mitted vital data for the first
35 min a re considered to belong to the catego ry
with high chances of survival for the rest of their burial duration.
All the burie d s ubjects, whose transc eivers are
techn ically not c apable of de tecting v ital data or
canno t d etect any for whatever reason, belong to
the category wit h u nknown chances of survival.
If you car ry the transceiver in a trouser’s pocket,
the de tectio n of vit al data is n ot poss ible due to
the al most no n-exist ent movements .
43
7.6 Rescue – Excavating the Buried Subject
Size the area to be dug out generously. Pay attention
to the presen ce of a n a ir pocket and avoi d t rampling
on top of the buried subject. A ccess the buried subject laterally. Digging must be p ractic ed as w ell. It
takes by far the most time.
Cut out blocks of snow with the shovel. The lead shoveler of the group should be relieved from time to time.
Rotating clockwise at given i ntervals is easiest.
42
Companion Rescue
7.5 Pinpointin g with Tran sceiver and Probe Pole
Pinpo inting the l ocatio n o f a buried subje ct is n ot
possi ble with a transceiver alone. The burial depth
and the orien tation of th e subject can be determined
easil y a nd quickly with a pr obe pole. Starti ng at the
point with the lowest dist ance reading or loudest
tone, appl y a spiral search p attern. Always probe at a
right angle to the snow surfac e.
If the buried subject is hit with the probe pole, the
pole is left in the snow. It serves as a guid e w hile
excavating the buried subje ct.
The buria l d epth is also a triage crit erion. In situations with limited resources deep burials are located
later.

45
7.7 Burial and Vital Dur ation
In case of a burial, the transc eiver records the burial
duration and detect s v ital data.
The Barryvox automatically displays the burial duration
as soon as the transceiver stops being moved. The
burial duration is displayed in hours and minutes along
with the time during which vital data was detected.
The display of the burial duration is also activated, if
the Barryvox stops moving outside of an a valanche.
By pressi ng any key in the SEND mode, you can recall
the buria l d ata of the five last resti ng periods of the
trans ceiver. T he resting periods are numbe red:
-1 most recent resting period
-2 second last resting period
-3 third last restin g p eriod
-4 fourth last resting period
-5 oldest restin g p hase
The curre nt resting phase is not numbered .
In multip le burial situations, the transceiver of a rescued subject should be turned off as soon as possibl e.

Human s a s Trigg er of t he Trap
The steep er and more shaded the slope is, the
greater the likelih ood of releasing a slab avalanche.
The likel ihood increases with larg e g roups without
spaci ng, frequent turns, and especia lly with falls or
jumps over cornices or o ther shock loading. Remote
trigg ering is possible startin g w ith the danger level
CONSI DERABLE, i. e. t he person triggering the avalanch e c an be standing dozens of meters outside of
the fract ure zone. This is fatal at the bottom of a
slope , because the entir e slope above can be
relea sed!
Note: Lig ht forest (with trees far apart enough to ski
or ride throu gh) will not protect you from slab avalanch es. Even rock outcropping s w ill not prevent t he
relea se of s lab avalan ches.
8.3 Precautions
8.3.1 Standard Safety Pre cautions
The follo wing stand ard safety precautio ns should
always be taken regard less of the danger level:
●
Avala nche transceiver on SEND,
along with a pr obe pole and shovel
●
Avoid fresh wind-deposite d snow
●
Consi der daily fluctuations in temperature,
espec ially in the spring
●
Const antly assess the conditio ns

Introduction to Ava l a n c h e T h e o r y
8. Introduction to Avalanche Theory
We would like to provide you with some basics on
this comp lex topic and recommend thoro ugh initial
and ongoi ng advanced a valanche training .
The Slab Avalanche: The Set Trap
Most wint er outdoor travelers trigger their own avalanch es. The snowpack is fragile. Slab avalanches
resem ble set traps: If we trigger it, th e t rap snaps.
Remem ber that a small slab of 100m3weigh s a bout
25 tons!
8.1 Hazard identifica tion
Very critical weathe r situations
The avalanche dange r i ncreases rapidly after storms
with new snow, wind, an d cold tempera tures. Slope s
with wind -drifted snow are especially danger ous!
Snow can also be moved by wind during nice weather. Th e f irst nice day after a snow event is particularly
dange rous. Most accid ents occur when a cold front
with stro ng winds and snow moves i n a fter days of
blue skie s a nd cold temperatures! In t his situat ion,
new snow amounts of 10 – 20 cm can constitu te a
criti cal situat ion that can last several days.
Rapid and strong warmi ng (downsl ope wind, rain) can
also caus e a n increase in avalanch e d anger, which
decre ases again with falling temperatures. If the
snowpack is uneven and weak, the danger is hard to
perce ive. T his is often the case with shallow snow
packs in the beginning o f w inter or during p eriods of
littl e p recipitation. In spring, the danger usually
incre ases as the day progresses: from low in the
morni ng followi ng a cle ar night to considerable in the
after noon.
8. 2 Risk A ssessment
Criti cal amounts of n ew snow
With the foll owing amou nts of new snowfall w ithin
1 – 3 days, the danger level is at least
CONSI DERABLE:
10–20 cm with adverse condi tions
20–30 cm with average cond itions
30–50 cm with favorable conditions
Adver se conditions
● Strong wind (> 50 km/h)
● Low temperat ures (< -8° C)
● Slope seldom traveled
Favora ble conditions
● Light wind
● Temperatures little below 0°C
● Slope traveled frequently

8.3.2 Minimize Stress on the Snow pack
Adequ ate spacin g i s an effectiv e m ethod to minimize
stres s o n the snowpack . Asce nding, the spaci ng
shoul d b e approxim ately 10 meters; desce nding
approximately 30 – 50 meters, due to the additional
stres s. Danger zones should be travel ed one person
at a time. Minimize t he stress on the snowpack by
makin g l ong turns. Avoid jumping!
