4.6 All Ships Call

This feature allows you to initiate a safety call or an urgency call to DSC-equipped
vessels without having their MMSIs in the directory or receive a safety call or an
urgency call.

Safety call: This type of call is used to transmit safety information (for example,
an overdue boat, debris in the water, loss of a navigation aid, and an important
meteorological message) to other vessels. This call is the same as saying
"Security, Security, Security".

Urgency call: This type of call is used when a vessel may not truly be in distress,
but has a potential problem that may lead to a distress situation. This call is the
same as saying "Pan-Pan-Pan" on CH16.
