| What action should a GMDSS Radio Operator take when SafetyNETTM Distress or Urgency messages are received by the vessel's EGC receiver? |
| A) No immediate action is required, as an audible tone will be generated at the beginning and end of the transmission and a paper printout of the message will be generated. |
| B) Aural and visual alarms are activated, and require manual deactivation. |
| C) No immediate action is required by the operator, since the transmission will be automatically acknowledged by the receiving vessel. |
| D) A periodic alarm tone will be heard until the radio operator prints the message from the unit's memory. |
