2-1. SCOPE.
This chapter provides operating information to SINCGARS airborne Non-lCOM and ICOM radio set operators.
It provides information on the self-tests that are a built-in feature of the SINCGARS radio and associated
equipment. It describes the appearance and function of the controls, indicators, and connectors on each of
the units of the radio sets. Also described is the keyboard used for entering information into the radios
manually. This chapter provides instructions for operating in single channel and frequency hopping modes.
These instructions cover such procedures as how to load SC frequencies, perform local fills, change net IDs,
receive and store ERFs, and perform late net entries.

2-2. INTRODUCTION.
The RT, RCU, DRA, AM-7189/ARC power amplifier, and ECCM fill device have self-test capability, Portions of
their circuitry are checked for proper operation. Some checks are initiated by the operator. Others occur during
normal operation.
2-3. RT SELF-TEST.
The RT performs a self-test when the FUNCTION switch is set to TEST. The results of the self-test are displayed,
The displays should be as shown in the figure below.
The "-----" display indicates that self-test has begun. The "E
-" display indicates that the ECCM module is
present. The ECCM module provides FH capability. If the module is not present, a dash (-) will be displayed in
