• Battery charging
The battery always charges in the unit when connected to an AC or DC power outlet, but the yellow
BATTERY light illuminates only when LifeStyle is turned off.
• Battery fully charged
When LifeStyle is connected to an AC or DC outlet and the flow selector is turned to OFF, the yellow
BATTERY light illuminates and displays continuously to indicate that the battery is fully charged. However,
when charging the battery for the first time, the battery should be left in the charger for 12 hours even if the
yellow light displays continuously.
• No inspiration detected
When LifeStyle is connected to a power source and does not sense breathing within a predetermined time
period, a constant alarm sounds, and the red ALARM illuminates. If this occurs, check the connection from the
cannula to the LifeStyle 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 an alternate source of
oxygen, and contact your Equipment Provider.
• Performance warning
The performance of LifeStyle can be affected by two conditions. The first is if the user’s breathing rate is
causing the threshold of the LifeStyle unit's capacity to be exceeded. The LifeStyle unit supplies a fixed
amount of high-purity oxygen. The amount of oxygen that LifeStyle supplies is dependent upon the flow
selector setting and your breathing rate. If the breathing rate is too fast for the flow selector setting, the
capacity of the LifeStyle unit can be exceeded.
The second condition that can result in decreased performance is a general unit malfunction. LifeStyle self-
monitors performance and alerts you if this occurs.
