Transportable Oxygen Concentrator Front
Panel and LCD Display
NOTE: For this procedure, refer to FIGURE 6.9.
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 36 or Troubleshooting on page 34.
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.
Breath Detect Indication
(Pulse Mode Only) The GREEN indicator light will blink off each time an
inhalation is detected and the transportable oxygen concentrator outputs a
measured pulse of oxygen.
Audible Alarm
The transportable oxygen concentrator is equipped with an audible alarm.
The audible alarm will activated in conjunction with Indicators and LCD
Display to annunciate Alarms and Warnings.
The transportable oxygen concentrator will also issue a steady beep when
all power sources are removed. The beeping will stop after 10‐20 minutes or
once a power source is connected.
The transportable oxygen concentrator will briefly turn on all three lights
and the LCD display and check for stuck buttons upon power up. It will
then output a brief audible beep to indicate the unit is operational.
