5.8. Printing Out of NAVTEX Parameter Status

For control purposes all selected parameters can be printed

out. This print out will show the frequency, filter, selected

messages and stations as well as a list of stored NAVTEX

messages.

5.9. Returning to Basic Standby Mode

This can be done by pressing the <EXIT> key

three

times or

the keys <8>, <8> and <3> in this sequence.

5.10. Displaying and Dealing with Errors

The SITOR code used by NAVTEX can recognise errors. Every

data field, to which a character has been assigned, will be

repeated and have a relationship of 4:3 bit. Only when both

data fields match and are valid does the corresponding

character appear as a capital letter. Should it be

recognised as valid only once, then it will appear as a small

letter. If both assigned data field characters be non-valid,

then it will appear as an * (asterisk). It is not common form of

expression. We are of the opinion that a small letter holds

more information than an asterisk *.

5.11 Termination of High Error Rate

When deciphering NAVTEX, the error rate of the decoded

signal will be examined. Should the acceptance rate be

exceeded, then the print out, if activated, will be

interrupted and the message will be automatically deleted

from the memory store.
