Transportable Oxygen Concentrator Front Panel and LCD Display
NOTE: For this procedure, refer to FIGURE 6.9 on page 30.
The front panel consists of LED indicators (red, yellow and green), control/adjustment buttons and a LCD display.
Indicators and Audible Alarm
There are three indicator LEDs located just above the LCD display ‐ green, yellow and red. The indicators could be on steady or blinking at different rates depending on the specific operating condition, including any warning or alarm.
NOTE: For detailed explanation and descriptions of the warnings and alarms, see
Warnings and Alarms on page 37 or Troubleshooting on page 35.
Green Indicator
The Green indicator is on when the unit is operating normally and providing good (>85%) oxygen purity.
Yellow Indicator
The Yellow indicator is typically on, or blinking, when there is a warning or non‐optimal condition present. The transportable oxygen concentrator could still be operating, but some user action may be required to return to normal operation.
Red Indicator
The Red indicator is typically lit, or flashing, when there is an alarm that requires the immediate attention of the user. Alarms typically result in the unit stopping with no delivery of oxygen.
