Portable Oxygen Concentrator
LOW BATTERY ALARM
As the battery pack power approaches a low level, a brief alarm sounds intermittently and the
yellow 25% battery gauge indicator light will illuminate intermittently. When this occurs,
connect the FreeStyle or FreeStyle 5 to an AC or DC power outlet, or change to an alternate
oxygen source.
When connected to AC or DC power, the concentrator will operate while recharging the battery
pack.
CANNULA DISCONNECT
When a FreeStyle or FreeStyle 5 is operating but does not sense breathing, a constant alarm
sounds, and the alarm light illuminates after 15 minutes. If this occurs, check the connection from
the cannula to the unit, make sure that the nasal cannula is positioned properly on your face, and
ensure that you are breathing through your nose. If the alarm continues to sound, change to
another source of oxygen as available, and contact your Equipment Provider.
BREATH RATE EXCEEDED
If your breathing rate causes the capacity of unit to be exceeded, a rapid alarm sounds every ½
second, and the alarm light illuminates red intermittently. When this occurs, the concentration
of oxygen that the unit is supplying is outside of the unit specifications. You should reduce any
physical activity, reset alarm by turning unit off and back on, and then if necessary change to
another source of oxygen as available, and contact your Equipment Provider.
GENERAL MALFUNCTION
If a FreeStyle or FreeStyle 5 has a general malfunction, a rapid alarm sounds every ½ second, and
the alarm light illuminates red continuously. When this occurs, the concentration of oxygen that
the unit is supplying is below unit specifications. You should change to another source of oxygen
as available, and contact your Equipment Provider.
