1.4 Emergency Calling
1.4.1 505 Emergency Calling
Inmarsat has introduced 505 Emergency Calling for the FBB terminals.
In a time of distress, a seafarer need only dial "505" and press either the offhook ( ) or # key-
selected for its similarity to "SOS" - to immediately contact a Maritime Rescue Co-ordination Centre
(MRCC).
Please note that 505 Emergency Calling is NOT GMDSS compliant. 505 Emergency Calling can not
be used if other phone or fax is used. Finish using phone and fax before dialing "505".
