🔍 Key Concepts

• Digital Selective Calling (DSC) distress procedures in the Global Maritime Distress and Safety System (GMDSS) • The dedicated DSC distress and calling channel for VHF • Difference between radiotelephony voice channels and DSC-only channels

💭 Think About

• Which VHF channel is reserved only for DSC (no voice) and is used to send the initial digital distress alert? • After a DSC distress alert is sent, on which channel is the follow‑up voice communication normally conducted? • Look at which answer choice pairs a DSC function with the correct dedicated DSC channel, not a normal voice working or safety channel.

✅ Before You Answer

• Identify which channel is internationally designated for VHF DSC distress, safety, and calling under GMDSS. • Eliminate any options that use a channel known primarily for bridge‑to‑bridge safety or ship‑to‑ship working traffic rather than DSC distress alerts. • Confirm that the chosen option refers specifically to DSC, not just radiotelephony, for the initial distress alert.
