You can clear the boom with the Boom Blowout function in the RCM. Access Boom Blowout through the diagnostic menu or directly from the main RCM run screen if the Master Switch is off. Tap the Boom Blowout button to get started.
Read the warning and take necessary precautions before starting the test. Acknowledge the warning when ready.
Turn on the Master Switch, and then tap the Start button.
Turn on a section with its section switch or on-screen button—depending on how your system is configured—and keep it on for enough time to clear the section. Be sure to monitor your pressure during this process. Cycle through your remaining boom sections until all sections are clear.
Turn off the Master Switch to stop the test.
