Which visual display notifies the operator laser energy is exiting from the First Defender RMX?

• A. Status Bar
• B. Alarm Light
• C. Laser aperture indicator Light
• D. Power indicator

Answer: (C)

Understanding how each indicator communicates laser activity helps you operate safely. The laser aperture indicator light is the direct signal that laser energy is exiting the aperture. It is typically positioned at or near the aperture so you get an immediate, location-specific cue that the beam is propagating. This makes it the most reliable visual notification for beam exit during operation.

Other indicators serve different purposes: the status bar shows overall system status and may indicate modes or connectivity but not the active beam; the alarm light is reserved for faults or safety alarms rather than normal beam activity; the power indicator simply shows whether the device is powered. Hence, the laser aperture indicator light is the best choice for signaling that laser energy is exiting.
