Battery Condition - mcmurdo E3 Owner's Manual

4.6 De-activation
If the E3 was activated by mistake or if the emergency ends then the E3 can be
reset back to its "ready" state as follows...
• Remove EPIRB from any water
and dry its sea switch contacts.
Wait 8 seconds for sea switch to turn off.
If EPIRB is still flashing then it must have
been turned on manually...
• Slide the switch cover fully to the right.
• Press and release READY button.
If EPIRB is still flashing then it has a fault.
Refer to section 5 on "False alarms".

4.7 Battery condition

If your E3 has been activated for a cumulative period in excess of 2 hours then its
battery will need replacing. This is necessary to ensure that the next time it gets
used it will operate for the full 48 hours required by government regulations. See
section 9.3 for battery replacement instructions.
4.8 Re-fitting E3 into wall bracket
The E3 is now in its "ready" state, but its sea switch is still armed and will activate if
it gets wet. To fully de-activate the E3 it must be returned to its mounting bracket,
where a magnet hidden in the bracket will make the E3 safe. Follow the appropriate
