B. It permits control of transceiver operations in response to an incoming DSC call.

C. It provides for the formatting and transmission of outgoing DSC calls.

D. It provides the scanning watch receiver capability on the 6 MF/HF DSC frequencies.

86J2 A "Distress Hot Key" MF/HF DSC Distress alert:

A. Will be transmitted on 2187.5 kHz or another DSC frequency, depending on the manufacturer.

B. Will always be transmitted on 2187.5 kHz and 8414.5 kHz to trip DSC alarms on the mandatory MF/HF DSC watch frequencies.

C. Will always be transmitted on 2187.5 kHz first to alert the nearest vessels and coast stations.

D. Will always be sent first on 16804.5 kHz to reach coast stations far away from the vessel.

86J3 A Distress Priority DSC call may be formatted and transmitted specifying and requesting:

A. Nature of Distress, vessel position, follow-on frequency, only voice follow-on communications.

B. Nature of Distress or alternate frequency but not both in a single call, vessel position or alternate frequency/emission but not both in a single call, voice or TELEX follow-up communications.

C. Nature of Distress or alternate frequency but not both in a single call, vessel position or alternate frequency/emission but not both in a single call, only TELEX follow-up communications

D. Nature of Distress, vessel position, follow-on frequency, only TELEX follow-on communications.

86J4 Which of these statements regarding a multi-frequency MF/HF DSC Distress alert is false?

A. Some units transmit on the mandatory MF/HF DSC watch frequencies first, and then on the others.

B. Some units transmit in ascending order of propagation radius to alert nearby ships or shore stations first.

C. May be transmitted in any order programmed by the GMDSSS operator.

D. Multi-frequency alerts work quite differently, depending on the manufacturer and require care and understanding of the feature.

86J5 To make a call to another vessel requesting voice communications regarding important company business, the GMDSS operator should:

A. Select Routine priority, enter other vessel's MMSI, specify legal alternate frequency, J2B emission and transmit the properly formatted DSC call.

B. Select Routine priority, enter own vessel's MMSI, specify legal alternate frequency, J3E emission and transmit the properly formatted DSC call.

C. None of these answers is correct.

D. Select Urgency priority, enter other vessel's MMSI, specify legal alternate frequency, F1B emission and transmit the properly formatted DSC call.

86J6 To make a call to another vessel requesting TELEX communications regarding important company business, the GMDSS operator should:

A. Select Urgency priority, enter other vessel's MMSI, specify legal alternate frequency, F1B emission and transmit the properly formatted DSC call.

B. Select Routine priority, enter own vessel's MMSI, specify legal alternate frequency, F1B emission and transmit the properly formatted DSC call.

C. Select Routine priority, enter other vessel's SELCAL for TELEX specify legal alternate frequency, F1B emission and transmit the properly formatted DSC call.

D. Select Routine priority, enter other vessel's MMSI, specify legal alternate frequency, F1B emission and transmit the properly formatted DSC call.
