Furuno FELCOM16 mini-C · OME-56380-G1
Match FELCOM16, communication unit IC-216, antenna IC-116 and manual OME-56380-G1 (4 June 2015). All lamps can light during the automatic startup test of about 30 seconds; do not restart merely to repeat it. POWER is green when powered; steady green LOGIN indicates login, flashing LOGIN is different; TX green means transmitting and ERROR flashing red means equipment error. Record SYNC/UNSYNC, login, GPS status, date/position, BBER, C/N and Antenna Power Supply separately. Antenna Power Supply NG can indicate an open or short cable: qualified marine service must investigate. Preserve logs; no reset, rewiring, forced region/login change, PV or SSAS test as troubleshooting.
