How to prepare a confidential file

If communicating with another FELCOM18, you can prepare a confidential message
by entering "S???-addressee code(-password):" in the first line of message text. You
can also receive confidential messages containing this header from a land subscriber
or any MES which uses the FELCOM18.
There are two types of confidential messages: message with addressee code and
message with both addressee code and password.
When the FELCOM receives a confidential message, the message is neither dis-
played nor printed immediately. To display or print the contents of a confidential mes-
sage, the recipient executes the procedure shown in section 5.2.3.
Addressee code and password
Caller and recipient agree beforehand on both the addressee code and the password.
The addressee code might be the title of the recipient; for example, CAPTAIN. The
password could be the classification of the message; for example, SECRET.
How to prepare a message with addressee code
Type the addressee code as shown in the illustration below and then type the text of
message.
