What is the percentage range indicated by Segment 1's green LEDs?

Segment 1's green LEDs are designed to indicate a high level of air supply remaining in the SCBA. Specifically, when the green LEDs are illuminated in this segment, they demonstrate that the air supply is within the range of 75% to 100% of capacity. This is crucial for users to be aware of as they assess their air reserve before entering hazardous environments. Maintaining a clear understanding of the air supply ensures that firefighters and other users can make informed decisions regarding their safety as they manage their breathing apparatus during operations.
