Chapter 2 is designed for the SINCGARS operator. It contains information that the
operator needs to know, except maintenance and special operations which are cov-
ered in other chapters. This chapter describes how to use the radio’s controls and
how to prepare the radio for operation. It also contains operator’s procedures for
single channel and frequency hopping operation,
loading data and receiving an ERF
for net opening. Although the SINCGARS radio demands more of the operator than
merely turning it on, operator tasks primarily involve entering data using the key-
board, using local fill devices, and responding to NCS messages. Once these steps
have been taken, the SINCGARS radio requires little of the operator other than listen
and push-to-talk. The Operator’s Roadmap and Functional Flow Charts in Appendix
A offer the operator graphic aids which may be helpful in learning and recalling basic
operator tasks.
