Which action is the fourth step in loading SINCGARS frequency?

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

Answer: (D)

When loading a SINCGARS frequency, you go through a sequence to set up the radio for the new entry. After you’ve chosen the appropriate mode and channel, you enter the frequency mode with FREQ. Clearing the current entry at this point is essential because CLR erases whatever digits are already in the frequency buffer and resets the input field. This guarantees you start with a clean slate, so the digits you type next are exactly the ones you intend to program, without leftovers from a previous entry. That’s why the fourth action is the clear step—it prepares the entry field for the new frequency data. The other actions are things you do earlier in the sequence (setting the mode and channel, then entering the frequency mode), but CLR specifically ensures a clean start before entering the new frequency.
