Power Supplies
FreeStyle can be powered in four different ways – the internal battery, a Universal AC/DC power
supply and an optional AirBelt battery belt in combination with the unit's internal battery.
1. Internal Battery: A rechargeable internal battery is located within each FreeStyle unit. When it
is fully charged, it supplies power to the FreeStyle unit for up to 3 ½ hours. An audible alarm
sounds when the battery power is getting low. The alarm is discussed in the Alarm/Light
Indicators section of this manual.
Battery Charging: To charge the internal battery, connect FreeStyle to either the Universal
AC/DC power supply and a 100-240 volt, 50/60 Hz AC power outlet, or connect it to a DC
power outlet in an automobile (boat, motor home, etc.). A discharged battery requires
approximately 3 ½ hours to fully charge. It is recommended to recharge the battery, even if
only partially depleted, as often as possible.
2. Universal AC/DC Power Supply: A Universal AC/DC power supply allows FreeStyle to be
connected to a 100-240 volt, 50/60 Hz outlet. The power supply converts 100-240 volt AC to a
DC voltage for the FreeStyle unit. When FreeStyle is operated with the Universal AC/DC power
supply, power from the AC outlet powers the unit and recharges FreeStyle's battery
simultaneously.
3. Optional AirBelt (External Battery Belt): FreeStyle can also be powered by an external
battery belt. This belt can be worn around the waist, and when used in combination with a fully
charged internal battery, supplies power to FreeStyle for up to 10 hours. The belt pack
connects to the FreeStyle unit's power inlet, and it can be recharged by connecting it to the
battery belt's own AC power supply.
When using the AirBelt with a fully charged internal battery, the FreeStyle's internal battery will
deplete before the AirBelt. The AirBelt must be connected to the FreeStyle unit before the
FreeStyle's internal battery is depleted. Observe and connect the AirBelt to the FreeStyle unit
before its internal battery discharges to 25% or less.
For oxygen concentrators equipped with batteries:
NOTE
MN131-1 rev C
1. When connected to AC or DC power, the unit's battery charges until it reaches full capacity,
either while the unit is operating or turned off.
2. If the internal battery fully depletes and the Oxygen Concentrator shuts down, the unit
cannot be restarted with the optional AirBelt. Should this occur, connect your Oxygen
Concentrator to its AC or DC power supply for a short period of time in order to provide
sufficient internal battery power to start the unit. AirBelt can then be connected to provide
additional run time.
