6.5 Every 4 or 5 years
If the EPIRB has a mandatory requirement of shore-based maintenance,
perform complete SBM service or replace the complete EPIRB. See chapter
6.8
The interval is 4- or 5-years dependent on the flag-state administration.
6.6 Every 10 years
Due to the harsh environment the EPIRB normally is situated in, Jotron
strongly recommends replacing both the EPIRB and the bracket after 10
years.
6.7 Hydrostatic release unit (HRU) replacement
The hydrostatic release unit shall be replaced within the end of the year
and month indicated on the side of the HRU. This is shown in the following
figures.
