MOBiMOBi is an advanced fail-safe transponder outboard system. It consists of a basic unit and up to eight active transponders for staff or important equipment. In operation, the base station sequentially interrogates each responder and then broadcasts its presence. If the crew member falls off the ship, the base unit will detect the drop in signal level and issue a high-intensity audible alarm. To help identify the missing crew member, the base station will continuously display the names of all currently logged-in crew members, the signal level of their transponder bracelets and their current status. Each transponder is powered by three AAA batteries and can be used continuously for several weeks. If the base station is turned off, the transponder will enter a dormant state with a service life of several years. Technical specifications: complete.
