Upon receipt of SafetyNETTM messages of the Distress or Urgency category on the ship's EGC receiver, what action is required by the GMDSS Radio Operator?
Manually reset the alarm.
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.
No immediate action is required by the operator since the transmission will be automatically acknowledged by the receiving vessel.
A periodic alarm tone will be heard until the radio operator prints the message from the unit's memory.
