On the RCU in the recorder section, which switch places the associated recorder into the proper operating mode?

• A. ON LINE
• B. ON LINE/MON EDIT/RECORD
• C. REC 1/REC 2
• D. OVERLAY/END

Answer: (B)

The switch that places the recorder into its proper operating state is the one labeled with three positions: ON LINE, MON EDIT, and RECORD. This control lets you choose how the recorder interacts with the system: ON LINE puts it in active, live operation; MON EDIT lets you monitor and edit the recorded data without disrupting the live flow; and RECORD actively writes new data to storage. Having all three modes available on a single switch is exactly what you need to set the recorder to the intended mode, which is why this option is the best fit. The other switches don’t provide the full set of modes needed: one is only a single mode (ON LINE), one selects which recorder unit to use (REC 1/REC 2), and the remaining option isn’t related to operating modes at all (OVERLAY/END).
