OPERATING YOUR BEACON
WARNING: This 406 MHz transmitter is authorized for use, only during situations of grave and imminent danger.
Deliberate misuse may incur a severe penalty.
Category I Beacons:
Category I beacons are designed to be automatically deployed and activated in the event of a vessel sinking. A
category I beacon may also be manually activated while in or out of its bracket.
Category I beacons deploy and activate automatically if the vessel (and the bracket) sinks to a depth between
4.9 ft (1.5 m) and 13 feet (4 m). At this depth, the HydroFix™ hydrostatic release unit (HRU) is activated and
the beacon is released from the bracket, allowing it to float to the surface. Continuity is then created across the water-
activation contacts and the beacon is activated.
Category II Beacons:
Category II beacons are designed to be manually deployed from the bracket and then activated manually or
placed in the water to activate automatically.
Two conditions must be met for a Category II beacon to automatically activate:
It must be removed out of its bracket.
It must be wet (i.e. placed in the water)
Either condition, by itself, will not automatically activate the beacon.
NOTE: Upon activation, transmission of the 121.5 MHz and 406 MHz signals will not occur until 50 seconds after
activation. After the first transmission, the 406 MHz signal will be continuously transmitted at 50-second intervals for a
minimum of 48 hours.
