When turning on the Receiver Transmitter (RT) of SINCGARS, what is the next step after setting the mode switch to SC?

• A. Place RF power switch to the desired level
• B. Place channel switch to MAN
• C. Place COMSEC switch to CT
• D. Place volume switch to the desired level

Answer: (A)

After turning on the RT and setting the mode to Single Channel, the next step is to set the RF power to the desired level. This controls how much transmit energy leaves the antenna, impacting range, battery life, and signal clarity. Establishing the correct power before you begin using the radio ensures you transmit at an appropriate level for the mission and environment. The other steps are typically done once you’re ready to establish or test a link: selecting the channel mode (manual vs. other channel options) and configuring encryption (COMSEC) are important, but they come after you’ve configured the basic transmit parameters. Adjusting the volume is for audio receive levels and can be done once the radio is operational, but it doesn’t affect transmission readiness the way setting RF power does.
