3-12. CIK.

The ANCD is a Class II Cryptographic Controlled Item (CCI). It contains a small, removable insert known as

the Crypto Ignition Key (CIK). With the CIK removed from the ANCD, stored SOI information can be read

from the ANCD display, but COMSEC/FH data cannot be loaded into or out of the ANCD. When the CIK is

inserted into the ANCD, it becomes classified at the level of the highest classification. The ANCD is designed

to prevent classified COMSEC/FH data from appearing on the ANCD display. When using the ANCD with the

SINCGARS radio, the CIK is normally not removed from the ANCD. The CIK is basically a special key

required to gain access to ANCD functions and information.

SUPERVISORY CIK. Each CIK is coded to operate only in one specified ANCD. When required,

communications supervisors may use CIKs which provide special access to keys not available when using

the operator CIK. This capability can be loaded into special supervisory CIKs by the Brigade LCU operator.

PROTECTING CLASSIFIED DATA. There are two ways to clear the ANCD of classified information. The

first and best is for the operator to press the red 'ZERO' button three times. This action clears the ANCD of all

stored data, SOI and COMSEC/FH. The other way is to remove the CIK, which clears COMSEC/FH data but

not SOI information.

A defective CIK is replaced when it is worn or electrically defective. The following steps describe the

replacement of the defective CIK (see Figure 3-2).
