G1 HUD Buddy Light
The G1 HUD is equipped with a buddy light that utilizes the top button on the regulator. The buddy
light on the regulator is the only buddy that does not light green. The buddy light will illuminate yellow
at Segment 3 of the pressure range. It will illuminate red when the pressure reaches Segment 4 or a
primary alarm goes off. Primary alarms are considered PASS alarms and primary thermal alarm. All
other alarms are considered secondary alarms and only alert the user.
G1 HUD Light Sensor
The G1 HUD is also equipped with an ambient light sensor that analyzes the surround light and
changes the intensity of the LEDs to ensure they are easy to see. The ambient light sensor is located
in the regulator. Light is captured by the regulator button and travels inside the regulator to the sensor.
There are multiple settings to the light sensor. Under bright light conditions, the LEDs are brightened
to their maximum intensity. When in very dark surroundings, the LEDs are dimmed to their lowest
intensity to ensure they do not blind the user.
