LIFESTYLE PORTABLE OXYGEN CONCENTRATOR

Alarm/Light Indicators
When the LifeStyle unit senses inhalation, a pulse of oxygen is sent through the nasal cannula. The green PULSE light
displays intermittently each time a breath is detected. There are no audible alarms or other lights on during normal
operation.
An audible alarm sounds if LifeStyle has a low battery, senses no breathing, or if performance of the unit is outside
specifications. If an alarm sounds, open the door covering the device controls to observe which lights are on. The light
and audible alarm conditions are explained in detail below and summarized on the chart later in this section of the
manual.
• Start-Up
A brief alarm sounds at start-up. LifeStyle begins to operate when the alarm stops.
• Low battery
As the battery power approaches a low level, a brief alarm sounds intermittently, and the yellow BATTERY
light illuminates intermittently also. When this occurs, replace the battery, connect LifeStyle into a DC auto
adapter outlet or an AC outlet, or change to another source of oxygen within five minutes. When LifeStyle is
connected to a DC auto adapter outlet or to an AC outlet, power from the automobile battery or from the AC
outlet operates the LifeStyle unit and recharges LifeStyle’s battery simultaneously.
• Discharged battery
LifeStyle does not produce oxygen when the battery power falls below a certain level. When this occurs, a rapid
alarm sounds and the yellow BATTERY light illuminates intermittently. In this case, replace the battery, connect
the LifeStyle to a DC auto adapter outlet or an AC outlet, or change to another source of oxygen immediately.
When LifeStyle is connected to a DC auto adapter outlet or to an AC outlet, power from the automobile battery
or from the AC outlet operates the LifeStyle unit and recharges LifeStyle’s battery simultaneously.
