What is the percentage range indicated by Segment 3's yellow LEDs?

Segment 3's yellow LEDs indicate a percentage range of 36 to 49%. This range serves as an important warning level for users of the SCBA, alerting them that their air supply is becoming critically low. Knowing this specific range is crucial for safety, as it allows individuals to assess their remaining air supply and make informed decisions about exiting hazardous environments before becoming compromised due to low oxygen. This feature is designed to enhance situational awareness in emergency situations, making it essential for SCBA users to understand the implications of the LED indicators for their safety and operational effectiveness.
