If communicating with another FELCOM 12, you can prepare a con- fidential message by entering “S???-addressee code(-password):” in first line of message text. You can also receive confidential messages containing this header from a land subscriber or any MES which uses the FELCOM 12.

There are two types of confidential messages: message with addressee code and message with both addressee code and password.

When a FELCOM 12 receives a confidential message, the message is not displayed and printed immediately. To display or print the con- tents of a confidential message, the recipient executes the key se- quences shown on page 4-23.

Explanation of addressee code and password

Caller and recipient agree beforehand on both the addressee code and the password. The addressee code can be the title of the recipient; for example, CAPTAIN. The password could be the classification of the message; for example, SECRET.
