You are on a ship in the Pacific ocean. What keyboard entry would you make on an Inmarsat-B terminal to obtain a TELEX connection via Santa Paula to another ship that is 300 miles west of San Francisco?

Correct Answer: Option C — 001+ 00582336657450+

For a TELEX call via Santa Paula (001) to a vessel in the Pacific Ocean Region (582), the operator uses the access code 001+, followed by the ocean region code 582 and the vessel's identification number. The + sign correctly terminates the sequence for the Inmarsat-B TELEX switching system.
