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.
If the internal battery fully depletes and the FreeStyle unit shuts
down, the unit cannot be restarted with the AirBelt. Should this
occur, connect your FreeStyle to its Universal AC/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.
If the FreeStyle power supply remains connected when the battery
is fully charged, the four LEDs will turn off within approximately 1
hour.
It may be necessary to initially connect the Universal AC/DC
FreeStyle power supply to the FreeStyle unit before the unit will
operate for the first time on battery power. Your Equipment
Provider may have already performed this step for you.
Use only AirSep Part No. FI144-1 for air intake filter for this unit.
Do not operate FreeStyle without the air intake filter in place. If a
second filter is provided, insert the "replacement" filter before you
clean the dirty filter.
AirSep does not recommend the sterilization of this
equipment.
