8.2.1 HUD Buddy Light
The HUD has a buddy light that uses the top button on the regulator. The buddy light on the regulator
is the only buddy light that does not light green. The buddy light lights yellow at Segment 3 of the pres-
sure range. It lights red when pressure reaches Segment 4 or a primary alarm occurs. PASS alarms
and primary thermal alarms are primary alarms. All other alarms are secondary alarms used to alert
the user.
8.2.2 HUD Light Sensor
The HUD has an ambient light sensor in the SCBA that analyzes the surrounding light and changes
the intensity of the LEDs to make them easy to see. In bright light, the LEDs are brightened to their
maximum intensity. In very dark surroundings, the LEDs are dimmed to their lowest intensity.
