2.1 Maintenance tasks

Servicing agents (Shore Based Maintenance (SBM) providers) are reminded that it is
their responsibility to ensure that the procedures herein are followed, that only OEM
approved parts are fitted, and that good common practice is observed.
False alarms caused by inadvertent activation must be avoided
The functions which can be performed by SBM providers are:

• Routine testing

• Reprogramming
• Message reading and verification
• Power measurement
• Battery replacement
• Leak testing
• HRU replacement
• Data recovery
• Fault diagnosis and repair
2.2 Routine testing
An EPIRB should be tested monthly by its owner to ensure functionality. Wherever
possible the EPIRB should also be inspected for mechanical damage.
In accordance with IMO guidelines (Circ 1040) an EPIRB fitted to a GMDSS
compliant vessel is recommended to undergo a yearly on board inspection.
In accordance with IMO guidelines (Circ 1039) an EPIRB fitted to a GMDSS
compliant vessel is recommended to undergo a five yearly SBM inspection.
Whatever the reason for the return of an EPIRB to a shore-based maintenance
agent, the EPIRB must be subjected to a full assessment before any other action is
taken. The agent has a responsibility to ensure the EPIRB is completely serviceable
and is fit for its purpose.
