For automatic activation of the EPIRB module, put the capsule in
the upright position into the water, and the transmission starts when
the seawater completes the circuit between the two external
electrodes (sea water contacts).
When the capsule is mounted in the automatic release bracket
mechanism, there is a safety switch in the EPIRB module, a reed
contact activated by a magnet at the FBR-3 bracket, which disables
the seawater contacts. See figure 3.1.5.
If submerged in water, the hydrostatic release mechanism will
release the capsule at a depth of 2-4 meters. The transmission will
start when the circuit between the seawater contacts is closed and
the capsule is out of the bracket.
The EPIRB module may be manually activated with the main
switch, and is then independent of seawater contacts. The EPIRB
module will also operate while placed in the bracket when
manually activated.
The capsule may easily be released from the mounting bracket
manually.
