In a firefighting context, what does a rapidly flashing "LO batt" message indicate?

A rapidly flashing "LO batt" message indicates that the battery needs replacement soon. This alert serves as a warning to firefighters that the power supply for their equipment is becoming critical and requires attention to avoid equipment failure during operations. This is essential in a firefighting context where reliable equipment is crucial for safety and effectiveness on the scene.

The rapid flashing means the battery's charge level is low enough to potentially compromise the functionality of devices used in emergency situations. Ensuring that batteries are replaced promptly helps maintain operational readiness and ensures that all equipment functions at optimal levels when needed.

In contrast, a fully charged battery would not generate a low battery warning, and malfunctioning digital gauges would not specifically communicate battery levels. Water flow restrictions are unrelated to battery status and would typically involve other indicators specific to water supply issues.
