Operating Instructions
1. Locate and position the FreeStyle 5 so that the air inlets and air outlets are not obstructed.
2. Power the unit from (a) the internal battery; (b) AirBelt; (c) DC outlet (i.e. automobile or motor boat); or (d) an AC
outlet (i.e. normal household electric). (Refer to the Power Supplies section of this Patient Manual.)
This device supplies high-concentration oxygen that promotes rapid burning. Do not allow smoking or open 
flames within the same room of (1) this device, or (2) any oxygen-carrying accessory. Failure to observe 
this warning can result in severe fire, property damage, and/or cause physical injury or death. 
Do not use your oxygen concentrator in the presence of flammable gases. This can result in rapid burning 
causing property damage, bodily injuries or death. 
Do not leave a nasal cannula on clothing, bed coverings or chair cushions. If the unit is turned on but not in use, 
the oxygen will make the material flammable. Set the I/0 power switch to the 0 (Off) position when the Oxygen 
Concentrator is not in use. 
Use no oil, grease, or petroleum-based or other flammable products with the oxygen-carrying accessories or the 
Oxygen Concentrator. Only water based, oxygen compatible lotions or salves should be used. Oxygen 
accelerates the combustion of flammable substances
.
It may be necessary to initially connect the AC or DC power supply to the oxygen concentrator unit before the 
unit will operate for the first time on battery power. Your Equipment Provider may have already performed this 
step for you. 
Charging of the battery may take several minutes after connecting the power to initiate, depending on the 
battery’s internal operating temperature. This is a normal condition and is intended for safe battery charging. 
This circumstance is more likely when the battery has been fully discharged
.
 
 
1. Connect your cannula to the oxygen outlet. 
2. Lift the dust cover on the unit. 
3. Turn the FreeStyle 5 unit on by pressing the 1, 2, 3, 4 or 5 button on the unit’s keypad for the liter flow prescribed by 
your physician. The green LED above the button selected illuminates. Each time you turn on the FreeStyle 5 unit, a brief 
alarm sounds. This indicates that FreeStyle 5 is powered for use. 
4. To change the pulse flow setting, press the appropriate button. It is normal to hear a difference in sound as you change
the settings.
5. To turn FreeStyle 5 off, press the button corresponding to the pulse flow setting light that is illuminated. When FreeStyle
5 senses inhalation, oxygen is supplied to you through your cannula. The time required to reach minimum oxygen 
concentration after turning on the FreeStyle 5 unit is approximately two minutes.
