- Release the EPIRB from the bulkhead bracket or enclosure when abandoning the vessel and embark the life raft.
- In cases where you have a manually activated EPIRB, remove "carry safe" collar from the EPIRB.
- Uncoil the lanyard from EPIRB and tie it to the life raft.
- Switch the EPIRB on manually using the activation switch (the way to do this depends on the EPIRB model) or, just throw it in water where it will be activated by the sea switch. The EPIRB is at its most efficient when floating on water.

An example of switching on an EPIRB (pull the tear-off tab up, then press the activation button and slide the switch left)
- The activated EPIRB should give a strobe light warning every few seconds (depends on the EPIRB model).
- Ensure that the EPIRB is not obstructed by anything that could prevent radio signal from reaching the satellite.
WARNING
The EPIRB must only be used in an emergency - in situations of grave and imminent danger.
CANCELLING A FALSE ALARM
If an EPIRB is activated by accident, it must NOT be switched off before informing a CRS or MRCC, for example by VHF radio. Only after being instructed to do so by a CRS or MRCC may the EPIRB be switched off. The EPIRB can be switched off following this procedure:
- Remove the EPIRB from any water and dry its sea switch
contacts. - If the EPIRB is still flashing then it must have been turned off
manually with the activation switch.
- If the EPIRB is still flashing then prevent its radio signal from reaching the satellite by cutting off or folding down the antenna and wrapping it in metal foil, a metal container or locker. Otherwise re-fit the EPIRB correctly into its mounting bracket or enclosure.
