Operating Procedure
If the vessel is not sinking but there is imminent danger, remove the
EPIRB from its bracket and activate it manually as shown previously.
Note that once activated it will flash immediately, but it will not
transmit a distress call for 50 seconds. This gives you a chance to turn it
off if you activated it in error.
Once activated the EPIRB must have its antenna as upright as possible
and it must have a clear view of the sky for proper operation. Laying it
on its side or placing it next to a metal bulkhead will impair its range
and may fail to alert the rescue services. Avoid handling the antenna, as
this will also impair performance.
5.8 Deactivation
If your EPIRB has been activated for a cumulative period in excess of 6
hours then its battery should be replaced. This is necessary to ensure
that in an emergency it will operate for the full 48 hours required by
international regulations. See section 0 for battery replacement
instructions.
If the EPIRB was activated by mistake or if the emergency ends then
the EPIRB can be reset back to its "ready" state as follows:
Fig. 5.9 – Deactivation of EPIRB
If the EPIRB is still flashing then it has a fault. Refer to section 6 on
False Alerts.
