Intermittent Mode With Continuous At Segment 3; Continuous Mode; Oscillating Mode - MSA G1 SCBA Operating Manual

8.1.2 Intermittent Mode with Continuous at Segment 3

Intermittent mode with continuous at Segment 3 is similar to intermittent mode except that in Segment
3, the LEDs flash until Segment 4 is reached.
To refresh the HUD during a segment, push the RESET button to display the pressure.

8.1.3 Continuous Mode

Continuous mode shows the pressure status at all times. The LEDs stay on so the user can always
look down and see the pressure. This mode uses the most amount of power, providing the shortest
battery life.

8.1.4 Oscillating Mode

Oscillating mode shows the pressure status on an interval basis. The LEDs cycle periodically from a
low-light to a high-light level. The LEDs are always on, but the brightness changes during the pressure
ranges of Segments 1 and 2. In Segment 3, the LEDs flash for 30 seconds, then oscillate until
Segment 4 is reached. In Segment 4, the LEDs flash until the SCBA is shut down.
