9.1
Communications related to search
and rescue operations such as distress alerts, coordination of operations,
local communications and positioning signals are never MSI, even when
(for some shore-to-ship alerts) they use the International SafetyNET
or NAVTEX services which are also used for MSI. This guide, therefore,
does not apply to them.
9.2
Search and Rescue operations
may, however, involve the broadcasting of MSI in the navigational
warning category, described in 4.2.2.6.
