conditions are explained in detail below.

to operate when the alarm stops.

To check the level of charge of the internal battery, press the BATT button on
FreeStyle 5’s keypad. The battery gauge / indicator(s) LEDs above the BATT
button illuminate from 25-100% to indicate the level (capacity) of the internal
battery. At less than 25% capacity, the 25% LED blinks.
2.3.3 Low Battery
As the battery power approaches a low level, a ½ second beep is emitted every
five seconds, and a yellow LED on the battery gauge / indicator(s) will blink
for a ½-second every five seconds. When this occurs, the patient is instructed
to connect the FreeStyle 5 AC or DC power supply or change to another
source of oxygen. The low battery alarm will continue for approximately 2
minutes before FreeStyle 5 stops operating.

When the battery is discharged, the unit shuts down. Before this occurs, a ½
second beep sounds every ½ second and the yellow battery LED blinks at the
same rate until any one of the 1-5 settings on the keypad are pressed. After the
