Furuno FELCOM 16 Manuel D’Utilisation

LRIT COMPLIANCE 

•  Power the equipment and keep it logged in at all times except for special occasions 

such as when the ship is dry-docked for repairs. Position information is automatically 
sent at fixed intervals, thus no operation is required. However, keep the equipment in a 
ready state to received commands from the LRIT data center. Combined use for routine 
messages, distress messages and SSAS (Ship Security Alert System) is possible.   

•  The source of position data for this equipment is its internal GPS receiver thus no 

external receiver is necessary.   

•  This equipment must be powered in the following manner. 

  - Conn the equipment to both main and emergency power sources (via AC-DC power                 
  unit PR-240). 

•  If an error message appears, take the necessary measures to restore normal operation 

as soon as possible. Shown below are representative alarms. 
  - WARNING: External NAV equipment failure.   
      Position data is not correctly input from the external GNSS equipment. Check the     
      GNSS equipment and the wiring between it and the FELCOM. 
  - WARNING: Internal GPS UNIT failure. 
      Position data is not correctly input from the internal GPS receiver. If this alarm occurs   
      frequently, have the set checked. 
  - WARNING: Synchronization loss. Please check the current Ocean Region. - 
  - WARNING: BBER over 80%. Scanning NCS start manually. 
      Problem with receiving the Inmarsat-C signal. Check if the current sea area is   
      suitable for your position. If it is not, change the sea area. If the area is suitable and   
      the alarm continues, check the antenna and antenna cable. Request service if the   
   problem persists.
