7 FULLY DISABLING AN EPIRB

In the unlikely event that your EPIRB refuses to turn off then it may
have a fault. Procedures for dealing with a faulty EPIRB are covered in
section 6 on false alerts; in simple terms you should do the following:
1. De-activate the EPIRB as described in section 6.2
2. Suppress its signal by removing the antenna and wrapping the
EPIRB in metal foil, as described in section 6.3
3. Leave for 3 days until the battery is used up.
We do not recommend any other course of action.
However, if it is absolutely necessary to fully disable an EPIRB (by
unplugging its battery), proceed as follows:
1. Take the EPIRB below decks into a dry area.
2. Locate a cross-headed screwdriver.
3. Unscrew and retain the 3 sealing screws.
4. Lift the lens dome off. This will lift the circuit board.
5. Avoid touching the circuit board if possible
6. Using fingers, unplug the three white battery connectors.
7. The flashing will now cease.
8. Collect all the parts and return them to your nearest service
agent.
