FREESTYLE PORTABLE OXYGEN CONCENTRATOR

Alarm/Light Indicators

When the FreeStyle unit senses inhalation, a pulse of oxygen is sent through the nasal cannula. The green light above the

selected pulse flow setting displays intermittently each time a breath is detected.

Additionally, when the unit is operating on and simultaneously being charged through the AC or DC power supply, the

FreeStyle unit's battery gauge/indicator(s) display the charge level of the battery and remain on for approximately one hour

after reaching a full charge.

An audible alarm sounds if FreeStyle has a low battery, if the cannula is disconnected, or if performance of the unit is outside

specifications. 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. FreeStyle 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 25% BATT

light also illuminates intermittently. When this occurs, connect FreeStyle into a DC power outlet or an AC

power outlet, or change to another source of oxygen within two minutes. When FreeStyle is connected to DC

power outlet or to an AC power outlet, the unit operates while recharging FreeStyle’s battery simultaneously.

The level of battery charge is indicated by the battery gauge/indicator(s).
