8. FOREWORD Thank you very much for choosing a Barryvox avalanche beacon Barryvox stands for quality conscious development production and testing State of the art technology has been applied for use under extremely hard conditions Due to the choice of personal settings the latest generation of avalanche beacons are ideally suited to the user s needs and abilities The default setting which can be restored at any time is the most appropriate one for novices and average users To operate the beacon in this setting only a single key will be used and the functions are limited to the very user friendly Digital Search Mode Advanced and professional users have the possibility to activate special functions in order to meet their individual requirements The beacon is fully compatible with all beacons that meet the require ments of the ETS 300 718 standard and operates at a frequency of 457 kHz An avalanche beacon does not provide you protection from ava lanches As an outdoor recreation alist you must keep yourself well infor med about avalanche prevention Also you should always plan your tours carefully Avalanche rescue must be practiced regularly to ensure quick success However it is only the means of last resort for the worst case Be aware that in spite of practice and all the technical advances only about half of all victims who have been The new Barryvox provides both digital and analog search modes

H MODE 14 Secondary Search Phase 14 1 Digital Search Mode The digital search mode offers the user optical guidance At distances above 40 meters the display prompts you by means of the lightning arrow to apply one of the Primary Search Phase strategies Even in this early phase a well trained rescuer may shorten the search path with the aid of the analog tones or recognize a multiple burial situation through the typical dual tones If the distance to the victim is less than 40 meters the distance and the direction are given The digital search mode requires less training and makes it easier to locate a victim 8 8 The microprocessor automatically adjusts the sensitivity of the receiver for optimum detection of the received signals This search mode requires less training and makes it easier to locate a victim Due to the laws of physics it is not possible to deter mine the distance with absolute precision The figures shown are only to be interpreted as relative Focus is therefore on the tendency to increase or decrease and not the absolute values Due to the changing shape of the flux lines in the immediate vicinity of a victim the direction display is suppressed at distances below 3 meters The pinpoint location is done by means of the distance display only Important points to be noted when using the digital search mode Hold the Barryvox horizontally in front of you Watch
