7-19C4:
Proper watchkeeping includes the following:
After silencing an alarm all displays and/or printouts are read, monitoring all required frequencies in the proper mode, notifying the Master of any Distress alerts.
Monitoring all required frequencies in the proper mode, setting the DSC scanner to 2 MHz, 4 MHz and 8 MHz for ships in the vicinity, notifying the Master of any Distress alerts.
Notifying the Master of any Distress alerts, setting the DSC scanner to 2 MHz, 4 MHz and 8 MHz for ships in the vicinity, monitoring all required frequencies in the proper mode.
Setting the DSC scanner only to the mandatory 2 MHz & 8MHz, maintain continuous watch on 2182.0 kHz or 4125.0 kHz, notify the Master of any Distress traffic heard.
7-19C5:
Proper watchkeeping includes the following:
Maintaining a proper GMDSS radio station log, understanding normal operational indicators, responding to and comprehending alarms.
Understanding normal operational indicators, setting the DSC scanner frequencies to minimize alarms, maintaining a proper log.
Responding to and comprehending alarms, logging out of Inmarsat-C terminals while at sea, maintaining a proper GMDSS radio station log.
Maintaining a proper GMDSS radio station log, setting the DSC scanner frequencies to minimize alarms, logging out of Inmarsat-C terminals while at sea.
7-19C6:
Which is true concerning a required watch on VHF Ch-16?
When a vessel is in an A1 sea area and subject to the Bridge-to-Bridge act and in a VTS system, a watch is not required on Ch-16 provided the vessel monitors both Ch-13 and the VTS channel.
When a vessel is in an A1 sea area and subject to the Bridge-to-Bridge act and in a VTS system, a watch is required on Ch-16 in addition to both Ch-13 and the VTS channel.
It is not compulsory at all times while at sea until further notice, unless the vessel is in a VTS system.
It is not always compulsory in sea areas A2, A3 and A4.
