FELCOM15/16/18/19 Inmarsat-C I-4 Satellite Migration www.furuno.com Pub. No. E52-01802-A (1806, AKMU) FELCOM15/16/18/19 Due to changes in the available satellites, caused by the end of I-3 satellite life-spans, current coverage regions have been, or will be changed to the new I-4 satellite coverage regions. This document outlays the coverage changes and the stages at which the changes that will occur, or have occurred. The following table shows the migration schedule from I-3 to the I-4 satellites. The migration process for each area will begin during 2018. For the details on the new coverage areas, see the reverse page.

Affected regions and their changes are outlined on the reverse page. ► The alert “Synchronization Loss” may occur immediately after the satellite migration. See the details on the reverse page. ► After the satellite migration, the support information etc. for Inmarsat users will use the new satellite region name. ► The schedule for the satellite migration is subject to change. See the following web site for the details. https://www.inmarsat.com/support/i-3-to-i-4-services-migration/ For FELCOM15/18 When the following alert statuses occur, the menu should be set manually (F7 [Options]→[Ocean Region]→[Auto] or own ship area) • The “Synchronization loss” status • The “UNSYNC” status when satellite migration to I-4 causes loss of satellite synchronization. Note 1: If the distress alert is transmitted during [UNSYNC] status, the satellite is searched for automatically and the alert is transmitted normally. Note 2: For FELCOM16/19, the satellite is searched for automatically so the manual search is not required. Ocean Region Auto West-Atlantic East-Atlantic Pacific Indian
