Battery Charging
Check to make sure your unit’s battery is fully charged before venturing out with FreeStyle for the first time or upon subsequent
use. To check the level of charge of the internal battery, press the BATT button on FreeStyle’s keypad. The battery
gauge/indicator(s) LEDs above the BATT button illuminate to indicate the level of internal battery charge (25-100%). Note: The
internal battery is charging whenever the unit is operating on AC or DC power. To charge FreeStyle’s internal battery, simply
connect its Universal AC/DC
p
ower supply into the unit’s power connection inlet (as shown in Figure 7). Be certain to first
properly align the power cord to this inlet. To do this, take note of the “D”-shaped plug of both the power cord connector and
the FreeStyle’s inlet connection. These must be properly aligned and when removing the power cord, the release button must be
pressed to remove it from the FreeStyle unit. This ensures that neither the unit nor the power accessories are damaged.
Optional AirBelt
The optional AirBelt, which can increase FreeStyle’s total battery duration up to 10 hours, requires approximately 3 hours to
completely charge when the external battery is fully depleted. To recharge AirBelt, connect its own AC power supply to the end
of AirBelt’s power cord (as shown in Figure 8), and the other end of the power supply into a proper AC power outlet. A separate
battery gauge/indicator for checking the level of charge on the AirBelt’s battery is located on this accessory’s cord and functions
exactly like the internal battery’s indicator on the keypad.
For oxygen concentrators equipped with the optional Airbelt:
3. The AirBelt does not need to be fully discharged before recharging. It is recommended to charge it after each use.
4. Depending upon the temperature of the AirBelt, it can take several minutes for the charging cycle to start after
connecting to power. This is a normal condition and is intended for safe charging.
