98. Deciphering. The cipherer, reading the radio groups off the
cipher form or off the preliminary cipher form, keys them; the copy-
ist reads the deciphered letters which light up and writes them
down as plain text on the cipher form or preliminary cipher form.
99. Dictating aloud is to be avoided.
100. Cipher forms. For outgoing messages, cipher forms are to be
used with the consecutive page numbers A ....
For incoming messages, cipher forms are to be used with con-
secutive numbers B...., C...., D...., etc. With aid of the various
designating letters B,C,D, etc, it is possible to arrange the
incoming messages by frequencies.
101. For incoming messages, the preliminary cipher forms are also
to be used as soon as the deciphering is completed, they are to be
pasted on to the cipher forms to which they belong.
l02. Aids. The supplementary Lamp Apparatus L for the Enigma
(Lampenzusatzgeraet L zum 5chluessel M) is to be used in cipher service
whenever it is available.

for the Army Enigma" When Using the Army Cipher

106. The cipher wheels of the Army Enigma are connected (geschaltet)
as are those wheels of the Naval Enigma which are designated with
the same numbers.
107. The following things are necessary for ciphering with the
a) Schluesselanleitung zur Schluesselmaschine Enigma (Cipher
Manual for the Army Enigma -- M.Dv 168.
b) Cipher of the Armed Forces and of the Authorities according
to the regulations entitled "Die Wehrmachtschluessel (The Armed
Forces' Cipher) -- M.Dv. 390.
c) Allgemeine Schluesselregeln fuer die Wehrmacht (General
Cipher Rules for the Armed Forces) -- M.Dv. 534.
(Translator's Note: Throughout this document, and in general,
the English word Enigma has been used to translate the
German Schluessel M, more properly translated Naval Enigma.
The German equivalents for what is here translated Army
Enigma are: Schluesselmaschine Enigma and Wehrmacht - M
Schluessel. When one of these is used the other usually
follows it in the German text in parentheses. - Tr.)
