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 AC power supply or DC power 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.

•  The FreeStyle’s internal battery will completely recharge from its fully depleted state in approximately 3 ½ hours, whether or not the 

unit is in use on AC or DC power. 

•  While charging a fully discharged battery, initially the 25% LED will start blinking rapidly for a few minutes, then start to blink at a 

slower rate every (1/2 second). 

•  The LED will continue to blink until 25% capacity is reached. The LED will then turn solid. 

•  Each of the four LEDs, 25% -100% , will blink as stated above, then turn solid when they reach their capacity. 

•  When all LEDs illuminate solid, the battery is fully charged and the LEDs will remain solid for a period of time, then all four LEDs will 

turn off.
