- Visually inspect the EPIRB and its mountings for cracks.
- Regular cleaning of the EPIRB and its mounting is recommended.
- Check that sea switches are clean.
- Check to ensure the lanyard is neatly bundled and firmly secured to the EPIRB and not attached to any part of the vessel.
- Check that the battery expiry label shows sufficient battery life to cover the next routine voyage.
- If you have automatically activated EPIRB check the HRU expiry date and confirm the enclosure cover can be easily removed.
- Perform standard self test. The EPIRB has a built-in test capability that can be used as a confidence check. This self-test confirms that the battery is healthy, that the GPS receiver (if included) and both distress transmitters are functional and that the strobe light is operational. It should be performed during the first 5 minutes of the hour, to minimise disturbance on the emergency channel. To run test sequence, TEST button should be pressed. At the end of the test sequence the EPIRB should give appropriate sound and light warning that depends of self test result (sound and light warnings depends of the EPIRB model).
If the EPIRB fails any of its monthly checks, it must be returned to the supplier or an authorised service agent.
If the battery is beyond its expiry date, the EPIRB must be returned to an authorised service agent for a battery change. It can be changed on board if its expiry date is due imminently or has passed.
If the EPIRB has been used in an emergency, it must be returned to an authorised service agent for a battery change.
