Which action is the seventh step in loading SINCGARS?

• A. Set MODE to SC
• B. Set CHAN to MAN, CUE, or Channel 1-6
• C. Press FREQ
• D. Set FCTN to SQ ON

Answer: (D)

In this loading sequence, you go through a fixed order of settings to prepare the radio for operation, with each action setting a specific parameter. The seventh action is to set the FCTN (function) to SQ ON, which enables the squelch function. Turning squelch on at this stage ensures the receiver mutes noise until a valid signal is present, helping verify the radio’s audio path and confirming the setup is progressing correctly. The other actions listed are earlier steps: choosing the mode, selecting the channel group, and loading the frequency. Those steps occur before enabling squelch, making the squelch activation the seventh step in the sequence.
