What is the correct process for sending text communications to an Internet destination using an Inmarsat-C unit?

The correct process for sending text communications to an Internet destination using an Inmarsat-C unit involves composing a text file, utilizing the SEND/REC function, and then specifying the recipient through the address book. This approach is effective because it allows the user to create a message in a structured format that can be easily sent over the Inmarsat-C system.

Using the SEND/REC function is essential as it is specifically designed for sending and receiving messages, facilitating the establishment of a connection to the required destination. The address book feature further streamlines the process, allowing users to store and retrieve Internet addresses conveniently. This is particularly useful for repeated communications, as it minimizes the risk of errors that could occur when entering addresses manually.

In contrast, alternatives such as calling up the file menu to insert the Internet address directly or attempting to attach a file without utilizing the designated SEND/REC function do not align with the correct operational protocol. Similarly, the assertion that Internet addresses cannot be reached from an Inmarsat-C terminal is incorrect, as this functionality is indeed available and widely used in maritime operations.
