After the SINCGARS RT self-test is completed, what should you do with the FCTN switch?

• A. Move FCTN switch to STBY or SQ ON
• B. Move FCTN switch to TST
• C. Set FCTN to OFF
• D. Leave FCTN at TST

Answer: (A)

After finishing the SINCGARS RT self-test, you want to return the radio to its normal operating state rather than leave it in test mode. The FCTN switch controls what the radio is actively doing. Moving it to standby keeps the unit powered and ready for use without engaging the test features, so you can immediately proceed to transmit or receive as needed. Alternatively, selecting squelch on ensures you can listen to incoming signals with noise suppression in normal operation. Leaving the switch in the test position or turning it off would keep the radio in test or disable normal operation, which is not desired after completing the self-test.
