Question 50G6
Element 7R (GMDSS-RO)When initiating a DSC call through the menu system what is the most likely information that will be displayed after making the first correct keystroke?
Explanation
When initiating a DSC (Digital Selective Calling) call, the radio needs to gather specific information about the intended communication. The "call setup menu" is the most logical first display because it prompts the operator for all essential parameters required for *this new call*. This typically includes selecting the recipient's MMSI, the type of call (e.g., routine, urgency, safety), and often the proposed working frequency.
The "priority menu" (C) is a component *within* the overall call setup, as you must select the priority for the call, but it's not the first independent menu. Displaying the "particulars of the previous call" (B) would be counterintuitive when starting a *new* communication. "The Telecom-1 menu" (A) is too generic and doesn't directly address the specific requirements for initiating a DSC call.
