8. If comparison with the correctly enciphered groups does not
suffice to restore the correct setting, then you must return
to the beginning setting (Message Setting) and repeat the
ciphering altogether. This process can however be shortened
by counting the number of correctly enciphered letters up as
far as the absolutely correctly enciphered group and then
pressing down any key the same number of times. After this,
the enciphering is continued.
9. In the interests of secrecy, the wheels are to be put out of
setting after every enciphering and deciphering.
There is to be certainty that the radio personnel end
other unauthorized persons obtain no knowledge of the Stecker
Connections of the Offizier or Staff Day Settings used.
If, after use, the Enigma is given back to the radio
personnel, then the valid General Inner Setting must be set
up. The Offizier or Staff Day Setting Stecker Connections
must be removed.
10. After the text of the message has been enciphered, the following
are to be inserted inP/Lbefore the enciphered groups:
a) Address
b) The word, "von"
c) Signature
d) The word "Offizier" in messages per Offizier procedure,
or the word "Stab" in messages per Staff procedure
e) Indicator letter for the Message Setting used, e.g.
Caesar.
11. Every enciphered message is to be checked by ciphering it back.
12. If the message is to be relayed further by radio, then the
form described in paragraph 10 is to be given to the radio
personnel.
13. Only the encipheredgroups resulting from the first stage and
the supplementary P/L items as per paragraph 10 may be made
accessible to the radio personnel.
Until cipher forms are issued for Offizier and Staff
procedure, the columns "Book Groups" and "Meaning". ("Bedeutung")
of the cipher forms used are to be cut off before the forms
are handed to the radio personnel. So also is the heading of
the column "Radio Groups', in order to avoid confusions in
this column, to be cut off.
