G1 Hud Alarm Status - MSA G1 SCBA Operating Manual

Option 4: Oscillating Mode
Oscillating mode shows the pressure status on an interval basis. The LEDs cycle from a low light level
to a high light level periodically. The LEDs are always on and the brightness changes over time during
the pressure ranges of Segment 1 and Segment 2. Once Segment 3 is reached, the LEDs flash for
30 seconds before going back to oscillating until Segment 4 is reached. Once Segment 4 is reached
the LEDs activate and stay flashing until the unit is shutdown.
