How would a Radio Operator of a vessel off the California Coast request Inmarsat Operator Assistance from the shore station via TELEX?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Type 11+ after receiving the GA+ from the LES Operator.

When utilizing TELEX via an Inmarsat-B Land Earth Station, the operator assistance request is initiated by typing 11+ after receiving the Go-Ahead (GA+) signal. This protocol informs the LES operator that the vessel requires manual assistance to complete the connection, adhering to standard GMDSS operational procedures for TELEX.
