Which indicators confirm PBE activation?

Explanation:
When a PBE is activated, you should observe two cues: a slight hissing sound and a blinking green service indicator light. The hiss shows the gas is being released from the unit, and the blinking green light confirms the PBE is activated and supplying oxygen. Relying on the sound alone isn’t enough—visual confirmation is required, and the green color is the indicator used for PBE status. A blue light or no indicators wouldn’t indicate proper activation, and a hissing sound without the blinking green light wouldn’t definitively confirm activation.
