Which statement about GMDSS MF/HF Transceiver frequency set-up is accurate?

The accurate statement regarding GMDSS MF/HF transceiver frequency set-up is that some consoles allow both manual entry and database recall. This flexibility is essential for operators as it enables them to quickly adapt to changing conditions or specific communication needs. By allowing both manual entry and the option to recall frequencies from a database, the transceiver provides the user with tools to efficiently handle various communication situations, such as emergency calls or routine communications.

Consoles designed for GMDSS typically come equipped with databases to simplify frequency selection for standard communications, but in cases where a specific frequency is not pre-loaded, manual entry ensures that operators can still engage in necessary communications. This capability is vital for ensuring uninterrupted service and safety at sea.

The other statements are less accurate because they imply limitations on frequency setup that do not reflect the operational practices used in GMDSS. While it is true that some systems might not always validate the accuracy of every database entry or may require manual input under certain circumstances, the existence of options for both manual and database methods provides essential versatility for maritime communication.
