RADAR TEST SET
ASSEMBLY AND PREPARATION FOR USE - Continued
TRANSPONDER MODE 4 PROGRAMMING PROCEDURE
The code loading process does not load the code of the day keys into the
Test Set. A sampling of 12 mode 4 interrogations is stored for each code: A,
B, Verify A, and Verify B. A Test Set which has been "Code Loaded" is not a
secure device. Code samples in the Test Set should be zeroized when no
longer required for testing to help prevent accidental use of the incorrect day's
a. To program the Test Set memory with appropriate mode 4 codes of the day (A, B, verify A, verify B) using
the model KIR-1C COMSEC device, proceed as follows:
(1) Connect the KIT/KIR-1C interface cable (PN: 55-1045-10) between the KIR-1C COMSEC device and
(2) Connect KIR-1C COMSEC device. Load key into COMSEC device.
The internal battery of the COMSEC device must be installed in order to
operate properly with the Test Set.
(3) Code loading can occur in the following ways:
If the operator does initial power up by inserting the battery or applying external power, the Test
Set autodetects COMSEC and loads the code.
Otherwise the operator can press buttons to go through the menus to load the codes. Refer to
