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 tra nscei ver d oes n ot pr otect you again st avalanches!

As a winte r out door enthu siast , you must consider all p ossib le avalanche prevention measures and plan your trips care fully. Companion rescue – the worst case – mu st be prac ticed freq uentl y. Under the s tress of a n acc ident , this is the only way you will be ab le to loca te and dig out a companion quick ly an d eff icien tly. Despite practice and all the techn ologi cal a dvanc ement s, by far not all of the compl etely buri ed avalanche victims are rescued! An avalanche burial is always life thre atening.

2. Initia l Setup

2.1 Emergency Plan

Befor e you use the d evice for the f irst time, remove the p rotec tive foil on th e fro nt si de an d stick the emerg ency p lan on the back of the batter y compartm ent l id.

2.2 Insert / Replace Batteries

Only u se alkaline (LR03/AAA) or lithium

(LR92/AA A) batteries of the s ame type. Always inser t 3 new batteries of the same type. In case these batteries ne ed to be removed, the same 3 batteries or 3 new batteries need to be reinserted. Nev er use recharge- able b atteries and always replace all the b atteries at the same time.

Make sure the l id is prop erly closed and that the devic e and the batteries stay dry. Per iodic ally inspe ct th e battery compartment. Cl ean o r dry it, i f neede d, since moisture can cause corrosion. Avoid touch ing t he co ntact s wit h you r han ds.

A rel iable power supply is crucial for the safe operation.

2.2.1 Importan t Points When Using Alka line Batte ries Type LR03/AAA

When stori ng or not using the trans ceive r for an exten ded p eriod of t ime ( i.e. in the summer), remov e the batteries and leav e the battery compartm ent o pen. The warr anty becom es vo id if batterie s have leaked! When r einse rting the batteries, use t he sa me 3 batteries or 3 new batte ries.

2.2.2 Importan t Points When Using Lith ium B atter ies Type LR92/AAA

Lithi um ba tteries are extraordinar y long-lasting , cold- proof and do no t lea k. The u sable ener gy in low temperatur es is high er co mpare d to alkal ine batteries. This batter y technology i s the best choi ce for t he application in a avalanche rescue transceiver.

2.3.3 Calibrat e device

Your PUL SE Ba rryvox

conta ins a n ele ctron ic co mpass which prov ides a rapid adjustment of the direc tion indic ator and extends the display range to 360 d egree s. To funct ion p roper ly, the c ompas s must be calibrated af ter e ach b attery replacement or after you have traveled for a long distance. The need to calibrate the c ompas s is autom atically detected when the batteries are replaced. This is, h owever, not th e case if yo u tra vel a long distance. Hold the d evice hori zonta lly a nd pr ess a ny key to start the calib ration procedure. Rot ate the horizontally held transceiver slowly and with constant speed clockwise until the message «Device calibrated!» appears.

Verify W-Link Region Setting

Verify that your PULSE Barryvox

is set to the appropriate W-Link region for your country (wireless radio link). Please pay attention to the information in the «Barryvox Legal and Regulatory Guide» and the chapter «W-Link». For countries without W-Link approval, transmission and reception of vital data is not possible. (Chapter «Triage Criteria and Vital Data»).

The Basi c Profile presents itself with an unchangeable range of functions and information which are specifically op timized for rudimentary trained users. In the B asic profile, the user only hears artificial beep sounds, it never plays the analog sound, therefore the tone inf ormation is always focusing on one burie d subject only, the one which is currently being searched for. During search, no vital data information is shown. The automatic selection of the closest buried subject replaces the possibility to manually choose in the list of buried subjects. The user does not have access t o analog mode, therefore the buttons during the sear ch are only used for marking (one-button user interfac e).

3.4.1 Analog Mode

The a nalog mode allo ws the rescuer to solve even the m ost c omple x mul tiple buri al si tuations and makes the PULSE Barr yvox

a ful l-fle dged avalanch e tra nscei ver. If the analog mode is set to «Manu al», the experienced rescuer can adjust the volum e man ually, wh ich can be ver y adv antageous in ce rtain situ ations. The setting “man ual” is as well requi red t o tak e adv antage of an increased search strip widt h as descr ibed in th e cha pter “Exten ded Searc h Str ip Width in Analog Mode ”.

3.4.2 Audio Su pport Fine Search

Durin g fin e sea rch, the search for beginners is supporte d wit h an acous tic t one, which leads you in the right dire ction . For rescue rs wh o can inte rpret the analo g sou nd, it is highly recommended to disable this digit al au dio s uppor t as the m ore m eanin gful analo g sou nd wi ll th en be available instead.

3.4.3 Fine Sea rch View (< 3 Meters)

In fi ne se arch range , the Barryvox supports the rescuer with the “assisted fine search” f uncti on, which allows a user-fr iendl y and prec ise f ine s earch . In ca se yo u do not l ike t his a ssist ance, you may choos e the sett ing “cross”, which give s you a dynamic c ross view durin g fin e sea rch. Alt ernatively, the setti ng “direction”, le ading you with the s tanda rd direc tiona l arr ow during fine search, may be u sed by re scuer s who are very fami liar with the p artic ular d istri butio n of the f ield lines in close proximity to a bur ied s ubjec t.

3.4.4 Auto-Revert to SEND

Auto- rever t to SEND switches the transceiver from SEARC H mod e to SEND mode if th ere i s no user inter actio n or major moti on fo r a s pecif ic am ount of time.

4.4 Turning the Device On

When the m ain s witch is moved from the OFF to the SEND or SEARCH positions, the transceiver is turned on. To slide the main switch from OFF to SEND or SEARCH, unlock the main switch by pressing down the button at the top. While star ting, the device conducts a self-test. The m icrop roces sor, the antennas, th e sen sors, and the d ispla y are chec ked. If the batt ery level is l ow, the s elf-t est w ill n ot ru n. If th e sel f-tes t is compl eted succe ssful ly, the display will show «OK».

The remaining battery level is displayed as a percentage. If th e sel f-tes t fai ls, an error message is di splay ed for 2 0 sec onds along with an a coust ic wa rning . The m eanin gs of the diffe rent error mess ages are descr ibed in th e cha pter «Troubleshooting».

Chang e bet ween Alkal ine a nd Li thium Batt eries

As soon as one battery is removed and a reinserted or replaced, the device tries to recognize the battery type (alkaline or lithium).

The following user interactions may be shown:

Only confirm this questions if you really inserted 3 new lithium batteries, which have never been used before in any other device.

Only confirm this question, if you have removed one or multiple batteries and reinsert now the same, in the meantime never for any other purpose used batteries (i.e. batteries you have removed over the summer).

Only confirm this question if you exclusively inserted alkaline batteries.

If you mix alkaline and lithium batteries, or try to use lithium batteries which have already been used in other devices, it is impossible to determine the battery capacity.

Just as in trad ition al an alog trans ceive rs, the analog t one i s rec eived by j ust o ne an tenna . The chang e in the d istan ce in dication can therefore devia te from the change in tone volume. D epend ing on th e rel ative orientat ion o f the tran smitt er to the recei ver, the tone volume and the distance indication may b oth d ecrea se wh ile a pproaching the burie d sub ject.

Therefo re, the volume of th e sou nd ca nnot be ta ken a s a d ecisi on criterion if yo u get closer or further away f rom t he bu ried subje ct.

The m ore s ignal s the re ar e, the longer the signal overl aps can last. The capa bilit y to autom atically detec t and isol ate signals from multiple buried subjects is t heref ore l imite d.

Numbe r of Buria ls

The c alcul ated number of burials is displayed below the l ist o f bur ied s ubjec ts. If the transceiver detects more signa ls th an bu ried subje cts i n the list, a + sign is ad ded b ehind the numbe r.

+Symb ol

The +sym bol indicates that signals are received from addition al buried subjects that cannot be isolat ed and ente red in the list of buried subjects yet. Turn off the tran sceivers of the buried subjects already found as soon as possible to simplify the isola tion of the remainin g signals.

Searc h Sus pensi on / “Stand still!”

Durin g the sear ch fo r mul tiple subj ects, signals may overl ap making it impossible to analyze the signal of a singl e bur ied s ubjec t. If the signal overlap l asts sever al se conds , the rescuer has to interrupt the proce ss te mpora rily to avoid devia ting from the optim al se arch path. The Barr yvox

will indic ate the n ecess ity t o sus pend (max. 15 seconds) the searc h by displ aying the word «Stop ». Stand still, and d o not move unti l the word «Sto p» di sappears, at which time you can continue to search.

Analo g Tone

Outsid e of the fine search rang e, the B arryvox always provides th e analog tone allo wing the rescuer t o verify the number of si gnals detected by the device . Counting the number of di fferen t tones provides the number of buried subj ects.

(Anal og Mo de = Manua l)

In th e ana log m ode ( with activ ated manual volume contr ol), the receiver sensitivity (volume) can be set manua lly. This makes acoustic searc hes p ossib le, as co nduct ed wi th tr aditi onal trans ceive rs. This mode is i. e. used when app lying „fin esear ch in a circle ”, in surroundings wi th st rong inter feren ce such as hi gh vo ltage pow er li nes o r in very comp lex burri al si tuations.

chapter «Extended Search Strip Width in Analog Mode»

By ac tivating the manual volume control in analog m ode, an analog tone is used for the group check , as well.

Once your Barr yvox is co nfigu red a ccord ingly, yo u can t oggle betw een s tanda rd an d ana log m ode w ith manua l vol ume c ontro l by brief ly pr essin g and holding b oth k eys a t the same time for three seconds.

The buri al duration is displayed in hours and minutes along wi th the time during which vital da ta was detected . The display of the burial du ration is also activated, if the Barryvox stops moving outside of an avalanche.

By pr essin g any key in the SEND mode, you can recal l the buri al da ta of the five last resting periods of th e tra nscei ver. The re sting peri ods a re nu mbered :

9.4.1 Triage

With l imited resources (few res cuers) it is not possible to locate and dig out all the buried su bjects at the sa me time. The question arises in whi ch order the bu ried subjects shall be re scued. S ubjects with

higher chances of survival shou ld be located and dug ou t first. Besides simple t errain factors, e.g.

drop o ver a cliff, in seracs or cr evasse s, collision with t rees etc., the burial depth and v ital data ar e import ant triage c riteria.

9.4.2 Vital Data Detection

The PULSE Barryvox

conta ins h ighly sens itive senso rs (g -sens or) t hat can detect slight motion of the b ody, such as a pumping heart or b reath ing lungs . Any motion within a certain maximum lag time is in terpr eted as vi tal d ata. The buried subject belon gs to the category with high chances of survival. It can be assumed that bu ried subje cts, which have sur vived the first 35 min, a re st ill a ble to br eathe (air pocket), a nd th erefo re ha ve incre ased chanc es of sur vival . At the same time , the detec tabil ity o f vit al da ta decreases due to hypot hermi a. There fore, buried subjects who have trans mitte d vit al da ta for the first 35 min are consider ed to belo ng to the category wi th hi gh chanc es of sur vival for the r est o f the ir bu rial duration.

All t he bu ried subje cts, whose transceivers are technically not capab le of dete cting vita l data or cannot detect an y for whatever reason, bel ong t o the c ategory with unkn own chances of survival.

Very criti cal w eathe r sit uatio ns

The a valanche danger increases rap idly after storm s wit h new snow, wind, a nd co ld te mpera tures . Slopes with wind-drifted snow are espec ially dange rous! Snow can also be moved by wind during n ice w eather. The first nice day after a snow event is p artic ularl y dan gerou s. Most accidents occur when a co ld fr ont w ith s trong wind s and snow moves in after days of blue skies and cold tempe ratures! In this situati on, new sno w amo unts of 10 – 2 0 cm can const itute a cr itica l sit uation that can l ast s evera l day s.

Rapid and strong warming (dow nslop e win d, rain) can a lso c ause an in creas e in avalanche danger, which decr eases again with falling temperatu res. If the s nowpack is uneven and weak, the dang er is hard to pe rceiv e. This is of ten t he ca se wi th sh allow snow packs in the beginning of winter or during perio ds of litt le pr ecipi tation.
