CHAPTER 3. OPERATION
3-1 Selector switch
The selector switch of this unit has following three positions.
(1) READY
Used to automatic activation. Distress signals are emitted immediately when the conductive switch
senses water after the Satellite EPIRB main unit is released from the automatic release bracket. That is,
the Satellite EPIRB main unit must float on the water surface to be able to emit distress signals.
(2) TEST
Used to check the functions of the Satellite EPIRB main unit. For details, see Section 3-6 “TEST”.
(3) ON
Used to manual activation. Distress signals are emitted when turning the selector switch ON.
NOTE
Manual activation is not possible unless breaking the stopper pin.
Therefore, broken stopper pin is the evidence that the EPIRB had been once activated manually. In that case,
replacing of the battery is required together with stopper pin.
NOTE
Release the stopper by breaking stopper pin to set the selector switch from READY to ON.
When broken stopper pin is found at periodical check, replacing of the battery must be required together with
stopper pin as it is considered that the unit had been manually activated and the battery had been exhausted.
The selector switch can be set to “TEST” without breaking the stopper pin.
